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.

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.

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.

I felt very well taken care of at Trendwerk. Many thanks to Marc Fiano for his professional and straightforward collaboration. I also thank Marco Reist for the creation of the professional sales dossier. I greatly appreciated the uncomplicated communication and the quick feedback. If I ever have a property to sell again, I already know who I will turn to! Thank you for your efforts and continued success!

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!
