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 purchase of our property went absolutely smoothly from start to finish thanks to Giorgio Frei. I particularly appreciated his proactive work style, quick communication, and high reliability. Questions were always answered promptly, information was presented transparently, and the next steps were clearly communicated. At all times, there was a feeling that he had the process under control and was actively taking care of all the details. This is incredibly valuable, especially when buying real estate. I would work with Mr. Frei again at any time and can recommend him without reservation.




Mr. Kalberer is very professional, knows the local market conditions very well, the sales dossier is excellently prepared, and he is very flexible with viewing appointments. I can highly recommend Mr. Kalberer.




It was very pleasant to work with Mr. Polesana, competent and factual, not intrusive and pleasant to deal with. I wish Mr. Polesana all the best.




Mr. Wollenmann accompanied us professionally during the purchase of our apartment in Jonen. He was always able to provide information with high expertise in response to our inquiries. Even after the contract was signed, he was available for any information we needed. Therefore, we can only recommend Mr. Wollenmann positively and look forward to the next purchase ;)








Very competent and helpful with everything. Also has good contacts with craftsmen who can assist with any potential renovations.








We were able to purchase an apartment that was mediated by Ms. Von Ow from onesta. From the first meeting to the final transfer at the land registry office, she advised us very competently and courteously. Both the seller and we as buyers are completely satisfied. Thank you very much
