Wir haben mit der Keller Immobilien-Treuhand AG sehr gute Erfahrungen gemacht: immer sehr schnelle Rückmeldungen, man kümmert sich um die Anliegen, immer pünktlich. Wir haben uns tets gut betreut gefühlt.

Our family-run property management business in Zurich was established in 1989, but we have worked in the construction and property sector all our professional lives. At the beginning of the 1980s, we ran an architects' office. A partnership with an expert in the building maintenance industry led us into a new business sector and a change in direction. Since then, we have exclusively managed and maintained fully furnished apartments in family owned properties. We work through personal consultation and offer great flexibility. Customers who have been loyal to us for many years appreciate the advantages of our family business, and our short decision-making paths and slim operation in particular. Our customer base mainly comprises people from the EU nations and overseas who have relocated to Switzerland for professional reasons, or who are living here temporarily. We can guarantee individual, efficient care for each and every one. We are members of the SVIT (Canton of Zurich), the largest association of property trustees in Switzerland.
