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.

After our trust in the previous agent was shaken by numerous negative experiences, we decided to work with Freddy Fallegger. His personable nature and many years of sales experience completely convinced us and corrected the negative image of agents. Freddy Fallegger managed to successfully sell our house in just 2.5 months, which his predecessor could not achieve in 9 months. We would gladly use the services of Freddy Fallegger as an agent again at any time. Keep it up, Freddy Fallegger!

I found Ms. Aregger to be very competent. I was always informed about every step. I would involve her again immediately.
