I can wholeheartedly recommend Ms. Nelly Olah. From the first conversation to the successful sale of my condominium, I felt excellently supported at all times. Ms. Olah worked extremely professionally, committed, reliably, and transparently. She was always reachable, answered all my questions competently, and regularly informed me about the current status. I particularly appreciated her honest advice, her pleasant and friendly manner, as well as her great commitment during the sales negotiations. Thanks to her experience and dedication, my apartment was successfully sold at a very good price. I sincerely thank her for the excellent collaboration and wish Ms. Olah continued success. I will recommend her at any time with full conviction.
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.
Ms. Tröndle was recommended to us by a relative who knew her through business connections as a second opinion, since we already had an offer for the sale of the apartment at that time. Ms. Tröndle made her first visit in April 2025, and it was immediately clear to us that we would proceed with her for the further process. Crucial was that she took our concern about finding a suitable apartment after the sale seriously and offered us her assistance, unlike the competitor. She implemented this immediately, and we were able to rent an apartment for June 2026 through her mediation as early as July 2025, even though the marketing of our apartment only took place in the fall. This was a great relief for us and meant even more trust in Ms. Tröndle. During the sales process, Ms. Tröndle always provided us with good advice and support with her suggestions and recommendations. The sale of the apartment was a great success, and we are very satisfied with it. We are happy to recommend Ms. Tröndle due to her high level of expertise, reliability, and friendliness.
Mrs. Scheer was extremely professional during the whole selling process. She took care of everything from the property advertisment to the handover to the new owners. I was very happy that she accompanied me through every administrative step. The selling process was very smooth and she does complete her duties until the very final step. Best regards, Fabrice Rolli
I was very satisfied with your service. She was very friendly, professional, and reliable throughout the entire process. My questions were always answered quickly and competently, and I felt well taken care of at all times. I can wholeheartedly recommend you as a broker.
Mr. Polesana advised us very competently on the sale of our apartment. His support was very helpful to us. The photos of our apartment as well as the online presentation were very professional. For months, we were able to rely on his assistance. We would hire Mr. Polesana again at any time for a real estate sale.
We were very satisfied with Ms. von Ostheim. Very friendly, competent, and efficient handling.
Excellent support – professional, committed, and absolutely reliable! During the purchase of my property in Wangen near Dübendorf, I was excellently supported from start to finish. I was particularly impressed by the exceptional commitment, high professionalism, and proactive coordination of all parties involved. From the communication and coordination with the sellers to the clarification of numerous details and the complex coordination with the banks and the notary, the entire purchasing process was managed confidently, efficiently, and with great care. Especially in a real estate transaction with many parties and demanding coordination processes, the true quality of a real estate agent is revealed. Here, not just mediation took place, but active responsibility was taken, solutions were found, and the entire process was accompanied until successful completion. I always felt well represented and supported. An exceptionally positive experience for which I would like to express my heartfelt thanks. My unconditional recommendation for anyone who values competence, reliability, personal commitment, and first-class service when purchasing real estate! Thank you very much for the excellent collaboration!
