Very competent brokers. Very friendly. They sold our apartment very quickly and easily. Highly recommended.




In May 2024, I purchased an apartment through Duss Immo GmbH and was accompanied throughout the entire purchasing process by Mirjam Heller. The collaboration was very pleasant, professional, and trustworthy from the very beginning. I would particularly like to highlight her always accommodating manner as well as her excellent availability. She responded quickly and reliably to emails at all times, so that any open questions could be clarified promptly. Furthermore, she communicated all relevant information transparently and openly. I always felt comprehensively advised. Through her competent support and commitment, the purchasing process was efficiently advanced. I would like to sincerely thank her for the professional guidance, transparent communication, and excellent service. I can wholeheartedly recommend the collaboration.




I got to know Ms. Weibel as a very friendly and helpful woman. I always felt comfortable and things progressed quickly. She was always open and quick to reach when I had questions. I would definitely recommend Ms. Weibel.








Very pleasant and friendly person, punctual, dedicated, competent, always informed about the next steps








Johanna is super friendly, easy to reach and fast to reply. As first time homeowners in Switzerland, she was patient, answered every single question no matter how small, and walked us through the entire process with professionalism.




Reliable and trustworthy - thank you very much for the excellent service.




A completely perfect experience. From the very beginning, we felt very well taken care of. He took care of every single detail, so the entire process went smoothly and stress-free. We particularly appreciated the honest, transparent manner that you can rely on 100%. We would recommend Michael Schwarzer at any time.
