Thank you very much for your support and assistance in the consultation and sale of our apartment in Grüningen. You have provided us with excellent advice and support in all real estate matters. We are very satisfied with the sales process and the sale proceeds. Thank you very much.




Professional and prompt handling of the apartment sale. Nice sales documentation. I can recommend it.




From the very first second until the end - and beyond - we experienced Stefan as friendly, knowledgeable, and always professional. The property was systematically and thoroughly evaluated. Two other independent assessments came in at the same price. It was good to know that we were not selling below value, but also that we were not trying to deceive anyone with an inflated price. The entire process was expertly managed and went smoothly. Communication was always timely and purposeful. The experience: simply first class!




I had a very good experience with Cosmos Values AG and the agile and goal-oriented Ms. Rena Wisler. Everything was very professional and perfect, which led to a good, fair sales result / sale price. The support for the buyers was also exemplary and of high quality. The entire formal sales process from the notarial purchase contract to the transfer of ownership was perfectly and stress-free organized. By the way: I found Ms. Wisler through a recommendation from enthusiastic acquaintances who previously used the services of Cosmos Values for the sale of real estate.




Mr. Plüer is very professional and competent. He was very flexible and always available to address our concerns. He always took the time to answer all our questions in detail. Moreover, he facilitated excellent communication between us and the sellers, which significantly eased the entire process. We felt well cared for and advised throughout the entire procedure.




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!




I bought my house through Jacqueline von Ow from onesta and am more than satisfied with the entire support. Throughout the entire purchasing process, I was accompanied by Jacqueline with great professionalism, personal commitment, and a lot of passion. She always had an open ear for my concerns and was always competent, reliable, and helpful when I had questions. I was particularly impressed by her honest, open, and friendly manner as well as the cooperative and trusting collaboration. I felt well taken care of and advised at all times during the entire purchasing process. If I ever decide to sell my house again, Jacqueline and onesta would undoubtedly be my first choice. A heartfelt thank you for the excellent support, the great commitment, and the overall pleasant collaboration.




As legal advisors to friends who had engaged the boutique real estate agency Neves Stierle & Horn for the sale of a larger special property, we have witnessed how professionally and amiably the trio has carried out their assignment. Convinced of the qualities of the three ladies, we engaged them for the sale of our own property. They executed the assignment in a short time to our complete satisfaction, both professionally and amiably. We felt well taken care of and supported at every stage of the sale. The buyers also greatly appreciated the collaboration with our agents. The three women accompanied both us as clients and the buyers throughout the entire process with dedication and expertise in a very pleasant manner. We can only highly recommend this team and would engage them again at any time if needed.




We were very satisfied with Andreas Graf and his support during the sale of our property. We particularly appreciated his willingness to help and his very good availability. He was always there for us with questions and took the time to explain and clarify everything understandably. At the same time, he actively took care of driving the sale forward, which we especially appreciated. We felt very well accompanied and supported throughout the entire sales process. We can recommend him with a clear conscience. Thank you very much, Andreas!




I would like to sincerely thank Alexander Riesch and his Bündner real estate team for the excellent service throughout the entire sales process of my penthouse apartment in Niederhasli. I was very impressed by their professional and friendly manner. I can highly recommend Mr. Riesch and his team. If I had another property to sell, I would definitely grant the mandate again to Bündner Makler. Thank you very much and continued success and all the best Marcel K.
