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.

















Mr. Meister took care of the sale of my property from A to Z. The sales process was professional, straightforward, transparent, and at a fair rate. I can highly recommend him. Thank you once again for the very friendly advice.








Mr. Zingg accompanied us throughout the entire apartment purchase and guided us through the process. We were very satisfied with his advice and found him to be extremely flexible. Thank you very much.

A real estate sale where everything fit together from the very beginning: the marketing strategy, the speed, and the result. Markus Wymann and his team managed to attract several serious and valuable buyers for my property in a very short time thanks to professional positioning and convincing marketing. The resulting competitive situation not only allowed for an exceptionally short marketing duration but also led to a sales result that exceeded our initial expectations. Markus Wymann has impressively demonstrated that successful real estate brokerage means far more than just listing a property for sale. Market knowledge, strategic approach, negotiation skills, and personal commitment have all played together excellently here. I particularly appreciated the trusting and collaborative partnership throughout the entire sales process. My heartfelt thanks go to Markus Wymann and his team for this extraordinary achievement. An unconditional recommendation!
