Gary Colman, Verkauf Wohnung in Zumikon ZH, 7. März 2019
We worked with Herr Grüninger who came highly recommended by friends for whom he also sold an apartment. From the first interaction, Herr Grüninger was attentive, detailed, and clearly experienced. He communicated promptly and proactively throughout the process, and after finding a buyer, went above and beyond to secure all the missing information needed to complete the transaction, helping us every step of the way when we were unable to do so ourselves.
I very highly recommend Herr Grüninger and plan to use his services for other properties.
