Thank you very much for your support and assistance in the consultation and sale of our apartment in Grüningen. You have provided us with excellent advice and support in all real estate matters. We are very satisfied with the sales process and the sale proceeds. Thank you very much.








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 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.












I would like to sincerely thank Mr. Lombardi for the excellent support in selling my old town house. From the very first contact, he was always competent and professional, very dedicated, and truly took the time for my wishes. I was particularly impressed by his transparent communication throughout the entire process. Thanks to his expertise and care, he introduced me to a perfect buyer for my old town house, who also made the purchase. I can only recommend Mr. Lombardi from BILO GmbH. Thank you once again.




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.




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.
