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.




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!




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!




Ich habe mein Haus über Jacqueline von Ow von onesta gekauft und bin mit der gesamten Betreuung mehr als zufrieden. Während des gesamten Kaufprozesses wurde ich von Jacqueline mit grosser Professionalität, persönlichem Engagement und viel Herzblut begleitet. Sie hatte jederzeit ein offenes Ohr für meine Anliegen und stand mir bei Fragen stets kompetent, zuverlässig und hilfsbereit zur Seite. Besonders beeindruckt haben mich ihre ehrliche, offene und sympathische Art sowie die partnerschaftliche und vertrauensvolle Zusammenarbeit. Ich habe mich während des gesamten Kaufprozesses jederzeit bestens aufgehoben und beraten gefühlt. Sollte ich mich eines Tages dazu entscheiden, mein Haus wieder zu verkaufen, wären Jacqueline und onesta ohne jeden Zweifel meine erste Wahl. Ein herzliches Dankeschön für die ausgezeichnete Betreuung, das grosse Engagement und die rundum angenehme Zusammenarbeit.




We can highly recommend Mr. Beck; he is very reliable, professional, and very dedicated. Thanks to his help, we were able to sell our house very quickly. Thank you for the good and reliable collaboration.




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.




Mrs Aarefa Amini was very helpful during my first real estate investment in Zurich. The quality of her service, the type of real estate selected and the high standards in deliveries met my full expectations. I highly recommend her as a partner for real estate investment and in partircular the real estate agency she runs. It was a pleasure to work with her and will maintain such business relationship for further acquisition.
