I was very satisfied and can recommend him without any doubts. He supported me well and I was especially happy in the end that he helped me with all the paperwork and took care of everything for me. At first, I thought I would find a buyer very quickly, but he already predicted to me that it can sometimes take a bit longer. I could always talk about everything and he was open to my suggestions.



Mr. Gaetano is a very good broker, friendly and competent, I can wholeheartedly recommend him, everything went smoothly.





I am/were an interested party. I have written to Mr. Barth multiple times requesting the floor plan and the price of this property. He does not respond. What kind of service is this? Even if the property is sold or if one does not want to sell the property to an interested party, one should send a brief notification. This seems unprofessional to me. It is a beautiful property, but without further information, one cannot proceed. The excuse that one is too busy does not hold up in today's time. 1 star is definitely 1 star too much for this agent. I hope Mr. Barth can read this review so that he might be willing to improve!!! Thank you for your attention C. H.







I purchased a property through GCT, Thomas Becker, and subsequently rented it out through them. Thomas Becker and the GCT team have completely convinced me. From the purchase to the renovation and rental, I was able to rely on his extensive experience at any time and always received very valuable and honest assessments. The communication was consistently efficient, straightforward, and at the same time very professional - you can tell that someone is thinking along. I would particularly like to highlight how Thomas Becker and the team work: always fair, solution-oriented, and with a clear focus on a win-win for all parties. This is definitely not a given in the real estate sector! I will be very happy to work with Thomas Becker and the GCT team again on future projects.








The support from Mr. Steiner during the purchase of our apartment was extremely pleasant, helpful, efficient, and very professional. I can only recommend him as an expert.




Reliable, - a man of his word. For excellent collaboration!




The collaboration with Ms. Schillinger was very pleasant and professional. She provided me with good advice and sold the property at a very good price. We found a suitable buyer and were able to arrange the handover of the property flexibly, as one never knows if there will be delays with a new build apartment. I can highly recommend Ms. Schillinger.





We commissioned the company Onesta Simon Leu in 2023 to sell our modern 5.5-room apartment and were very satisfied from the very beginning. Already during the first conversation, the company made an extremely serious, competent, and trustworthy impression. Throughout the entire sales process, we were always well taken care of and regularly informed about the current status. The communication was always open, transparent, and straightforward, so we were always well-informed. The sale of our property ultimately proceeded to our complete satisfaction. We sincerely thank you for the professional support, great commitment, and pleasant collaboration. We can wholeheartedly recommend this real estate company and would work with them again at any time!
