The company topka GmbH received the assignment from me to sell my property (single-family home) promptly and at a good price. Mr. Adrian Kälin executed this assignment professionally and very efficiently in all respects and sold the property within two months. I can highly recommend Adrian Kälin and would like to take this opportunity to thank him once again.
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 can highly recommend Hanspeter! His performance was simply outstanding. The communication was always friendly, clear, and professional – I haven't experienced anything like that in a long time. Hanspeter is a real estate consultant who impresses with a lot of expertise, commitment, and humanity. Thank you very much for the great collaboration!
I bought a plot of land from Mr. Hager where I was later able to build a large apartment building. Mr. Hager is very competent and helpful, all promises were kept, and the entire purchase process went smoothly. Thank you for that.
