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!




"The collaboration with Roger Kielholz was absolutely outstanding from start to finish. His professionalism, transparency, and exceptional commitment made the entire sales process significantly easier for us. Mr. Kielholz communicates clearly, reliably, and always on an equal footing. We were particularly impressed by his expertise in the Swiss real estate market as well as his ability to support both buyers and sellers in the best possible way. Thanks to his thorough preparation, his network, and his negotiation skills, we were able to sell our property not only quickly but also at an excellent price. We felt well advised and personally cared for at all times. We can wholeheartedly recommend Roger Kielholz as a real estate agent and would work with him again at any time."
