We had a very good experience with Stefan for the purchase of our house in Conthey. He was available, responsive, and professional throughout the process, always ready to answer our questions and assist us with the various steps involving the seller, the bank, and the notary. We particularly appreciated his follow-up, his availability, and the fact that he remained present even after the sale to help us with the final documents and procedures related to the house. We are very satisfied with his work and we can recommend him without hesitation. Thank you again, Stefan, for your support and trust!

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.
