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!




In October of last year, we purchased an apartment and were accompanied throughout the entire process by Marianne Gubler. Communication was always absolutely top-notch, we could always rely on her advice, and she showed a lot of patience and professionalism. This also applies to dealing with other involved parties (my bank, various offices, etc.): Ms. Gubler always communicated excellently and arranged everything necessary without any issues. In short: Anyone who has Marianne Gubler by their side for such a large and important transaction can sleep soundly.




In 2024, as an inheritance community, we had to sell the family home in Amriswil TG and commissioned Manuel Grieder, Real Estate, 8803 Rüschlikon for this. We were impressed by how professional and focused the tendering and negotiations were, culminating in a successful conclusion in December. We can only recommend this company. Charles Grieder




Mr. Fabio De Marco conducted the sale of our apartment with great commitment, competence, and friendliness. We thank him very much for his work.








Mr. Maranta provided us with excellent support in the sale of our house. Within just about 2 months, the sale was completed to our utmost satisfaction, thus opening the way for us to purchase a condominium. We thank Mr. Maranta for the professional support in all matters that led to a satisfactory conclusion. We can only highly recommend Mr. Maranta and the Griesser company at any time. A big thank you for everything.




**All-Inclusive Package** A huge thank you to Mr. Meier! I entrusted Mr. Meier with my property and was thrilled. From the first conversation to the notary appointment, I felt excellently advised. I was particularly impressed by his market knowledge and honest communication. Anyone looking for a reliable broker is exactly right here.




I can wholeheartedly recommend Ms. Marina Frei. She accompanied the sale of my building land professionally, reliably, and with a lot of personal commitment. The communication was always pleasant, transparent, and straightforward, and I felt very well taken care of throughout the entire sales process. I particularly appreciated her competent advice, her excellent availability, and the careful handling up to the successful completion. Thank you very much, Ms. Frei, for the pleasant collaboration and your dedication!








I was very satisfied and can recommend him without any doubts. He supported me well and I was especially happy in the end that he helped me with all the paperwork and took care of everything for me. At first, I thought I would find a buyer very quickly, but he already predicted to me that it can sometimes take a bit longer. I could always talk about everything and he was open to my suggestions.
