A few words to summarise what has so far been a highly effective partnership: J&J Properties listens to our expectations and responds promptly and precisely, both in its communication and in the answers provided to our questions and uncertainties. Its assistance in finding prospective tenants has also been invaluable and successful. The tenancies and everything they entail are managed proactively and competently, helping landlords reduce the stress that can arise from letting their properties.

A very good experience with J&J Properties! They were always there whenever I had questions. They are highly responsive, and everything was concluded quickly. Absolutely nothing to complain about!

A highly professional and efficient team! They presented a well-structured sales file, with excellent-quality photographs, and provided outstanding follow-up with the authorities, notaries and buyer.

In terms of communication, everything went extremely well. Whenever we sent an email, we received a prompt reply. Everything was very professional, and the entire process went smoothly.

A highly professional agency providing excellent service. The sale of our property was handled quickly and efficiently, with excellent communication. Thank you again!

I had an excellent experience with Carole. She is incredibly kind, highly motivated and truly understanding. Throughout the process, she listened carefully to my needs and always took the time to answer my questions.

Very satisfied with the work carried out by J&J Properties for the sale of our house in Brussels: they are quick, efficient and professional, and use cutting-edge technology!
John works with diligence and integrity, fundamental qualities for an estate agent.

Excellent service, with motivated and helpful employees who work with the client to find solutions.

This is the second time in four years that I have called upon JJ Properties to find housemates for our family home.
Pauline handled my case and managed to find the right profiles (five or six people) fairly quickly. Thank you, Pauline, for your kindness and professionalism. It was very reassuring to know that my house was in your hands: you listen very carefully to the owner, and your intuition when selecting candidates enabled me on both occasions to give an enthusiastic yes to the group you presented to me in 2021, as well as to the group presented very recently in 2025. I highly recommend this agency and Pauline.

A highly professional and, above all, personalised service. John is reassuring, ambitious and extremely available. We were delighted with the advice we received regarding the sale of our property in Brussels. I highly recommend them!

Precise and thorough work!

J&J Properties is an agency like few others! Dynamic, flexible and 300% professional. I would particularly like to thank Pauline Preud'homme for her professionalism and adaptability. It is a genuine pleasure to work with professionals like these.

The service is highly professional while remaining warm and friendly. I was impressed by the marketing tools used and by their valuation expertise. My property was sold within a week, without conditions, for an amount 15% above the valuations provided by two competing agencies.

Everything went extremely well. The estate agent gave me excellent advice and listened very carefully to my needs. We also had excellent communication throughout the process. In addition, I was impressed by the estate agent's level of expertise: he was very knowledgeable and was able to answer all my questions.

Thank you to Carol for her positive attitude and professionalism in marketing our property! We were more than satisfied and wholeheartedly recommend J&J!

Hello, I highly recommend J&J Properties for their professional service, friendliness, speed and availability. I dealt with one of their agents, Vincent Annez de Taboada, whom I warmly recommend! I wish the agency and all its agents continued success :)

After years of searching for the ideal home and dealing with just as many estate agents, we happened to meet John and his team during one of our viewings. At last, genuine professionals who are at your service and listen to you! From then on, it seemed only natural to work exclusively with them.
The results soon followed: a new home just as we wanted, in the area of our choice, and a quick sale of our first house. Thank you to the J&J Properties team.

From the outset, the information provided has been clear and comprehensive, and there have been no unpleasant surprises since our collaboration began almost a year ago, I believe.
Whenever there are questions or matters to resolve, they are dealt with quickly and without unnecessary excuses, which is honestly more than appreciated!
I wholeheartedly recommend this agency!

An outstanding agency with in-depth knowledge of its cases, excellent follow-up and objectivity, all delivered with tremendous courtesy and warmth! Highly recommended!

A friendly, approachable agency whose team is available and welcoming; you cannot fail to be impressed by your experience of working with J&J Properties!

Excellent availability and service!! Very pleased to have found our home with Jj Properties.

Two good experiences with J&J in Brussels already. I recommend them!

Fantastic team! Clear, straightforward and precise communication! A smooth and swift process!
In short, complete peace of mind!
Thank you, J&J, and see you again soon 👋

Well done for your swift response and efficiency! And for being so kind as well!
Thank you for everything!

We were not familiar with this agency, which had been recommended to us. We were extremely satisfied, as our property was let quickly and all the administrative work was completed properly.

I had a very good experience with J&J Properties! They always listened, and whenever I had a question, I never had to wait long for an answer. They took excellent care of me and were very responsive.

Perfect!

My husband and I were entirely satisfied with our collaboration with Mr de Troyer, and we warmly thank him for all the qualities—availability, friendliness, straightforwardness and expertise—that make him an excellent estate agent. We wish him every success in his future professional activities within the agency he manages alongside colleagues whom he holds in high regard.

Everything went well. I have no complaints. They were always available when needed.

We had a good experience with Vincent. The collaboration went very smoothly. I have no complaints whatsoever.

I have used J&J several times and everything has always gone very well! A great, highly professional team!

Communication was excellent! Caroline was genuinely very kind. I work a lot, and Caroline always found a solution for us. She always explained everything very clearly, and we received the keys very quickly too. It was great!

I called upon J&J Properties and John to sell a house. John was highly efficient and provided excellent follow-up. The team is dynamic and professional. I highly recommend them.

Thank you to Caroline for her excellent follow-up and responsiveness when letting a property in Ixelles. The flat is magnificent.

Excellent communication: straightforward and efficient, while maintaining a relaxed atmosphere that makes it easy to focus pleasantly on what matters. It is reassuring to finally see these qualities in this industry.

I had a building to sell in Schaerbeek. The building no longer met current standards and required a complete renovation. Thanks to an assessment of the building's potential, it sold in record time and for more than expected! It was advertised on Friday and sold on Monday! I did not have to handle any of the formalities; John and his team took care of everything. A huge thank you.

Professional and very friendly! Always given a warm welcome.

Unlike other agencies where staff do not even bother to answer the phone, I was able to speak to a knowledgeable person who spoke perfect English. I highly recommend this agency.

I had a very good experience dealing with the agency when renting a property in Brussels. I would use their services again in the future!

I have been using J&J Properties to manage my flats for five years now. I can confirm that tenancy agreements are followed up very well and accurately, and that communication is very smooth. Kind regards, Jos Verlinden

From our very first contact, dear John, I had the feeling that we would get along and that I could trust you. My instinct did not let me down. You are a team of professionals, but that is not all: your strength lies in your personal approach and your ability to listen, which is greatly appreciated, because selling your property also means saying goodbye to part of your life. Together with your colleague Carol, you handled everything brilliantly. All I can say is THANK YOU.

An agency with responsive staff who provide good advice!

I had the pleasure of working with J&J Properties and cannot recommend them highly enough. Caroline is an exceptional estate agent who truly cares about her clients and goes above and beyond to ensure that they have a positive and successful property experience.

Throughout the entire process, Caroline was professional, knowledgeable and communicative. She was always available to answer my questions and provide guidance, and she made the process as smooth and stress-free as possible.

Regards,
Manish Balani

I rented a studio through J&J Properties in Brussels.
The rental process went smoothly.
During my stay, communication with one of the agents, Caroline Loly, was perfect.
Afterwards, the handover and inventory process was similar to when I moved in, and I was not charged any unexpected fees.
I am very pleased that I rented a flat through J&J and worked with Caroline. I can honestly recommend them.

Probably the most reliable agency in Woluwe-Saint-Pierre. Well done for the efficiency of your responses and for your expertise in Woluwe. I was genuinely impressed!

The collaboration went very smoothly. The estate agent was always easy to reach & everything was arranged quickly.

My fourth or even fifth experience with JJ Properties and, as always, outstanding service, a professional approach and a highly committed team! Special thanks to Pauline for her drive, experience, availability and highly effective work!

A fantastic, very friendly team.

Renting through J&J Properties was a perfect experience! They are very helpful and respond immediately to all my questions. Alexandre and Sylvie are lovely people!

A dynamic agency!

So far, everything is going very well with J&J Properties; everything has been handled as it should be.

A dynamic and, above all, proactive agency. You can really tell that listening to clients is the cornerstone of their work. Transparency, attentiveness and efficiency sum up J&J perfectly. Thank you!

I really appreciate J&J's professionalism and attitude. I would certainly recommend their services to my friends.

Excellent multilingual service. A dynamic and professional team.

Our experience with J&J Properties has been outstanding, especially our interactions with Caroline. From the moment we decided to rent with J&J Properties, the process has been remarkably smooth and stress-free, making our transition into our new home an enjoyable experience.

Caroline, in particular, has truly stood out. Her commitment to ensuring that everything works seamlessly in our apartment has been nothing short of impressive. Whenever we encountered any issues or questions, Caroline was there to promptly address them, demonstrating her dedication to her role and our comfort as tenants. Her exceptional assistance and dedication have made us feel valued and well cared for as tenants.

What truly sets J&J Properties apart is their responsiveness, a quality that, in our experience, surpasses our previous dealings with other agencies in the same complex. The contrast in service has been striking, and it is clear that J&J Properties prioritises their tenants' satisfaction.

We are delighted with our decision to rent through J&J Properties and would highly recommend their services to anyone seeking a smooth and pleasant rental experience. Thank you, J&J Properties, for making our new apartment feel like home!

J&J Properties is a truly wonderful agency that I was lucky to find. They did everything they could to help me; without them, I would almost have ended up homeless. They truly did everything possible to ensure that I got the flat, and I am immensely grateful to them.

Very responsive. Friendly interaction.

Excellent team, communication and follow-up!

A young, honest and highly dynamic team. Hard workers who do not count the hours. They also have effective digital management tools! Put your trust in them!

Great team and excellent services

Well done on providing professional and efficient property management.

Highly professional and very responsive

My experience was very good, and the estate agent was quick to answer questions. They were also very trustworthy.
