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.












The collaboration with Cornelia Fischbacher was very pleasant. She is very competent, reliable, and supported us excellently in all matters. Cornelia Fischbacher also explained everything very clearly. It was very relaxed from the beginning to the conclusion.




The collaboration was contractually regulated at the beginning, the initial situation and the conditions were clearly clarified. The property was advertised locally and on various platforms. If there was interest, the property was shown, if necessary, multiple times. Due to the solid knowledge from the banking sector and land registry, questions from potential buyers could be competently clarified. The flow of information was always present, and the collaboration was very pleasant. As a seller, I was supported and accompanied from the assignment to the signing at the land registry office. I would give the assignment to Ernst Zwingli again, thank you very much!












The company Zaphin, led by Mr. Nussbaum, are the professionals in the Zurich Oberland area. Very pleasant and balanced, and the team is highly professional. The apartments were sold remarkably quickly. The buyers were also very satisfied.
