We experienced Sandra Hinnen as a very reliable contact person. Our wishes and ideas were discussed and implemented, and we were continuously and promptly informed. She showed genuine interest in helping us sell the apartment to a suitable buyer, whom she connected us with after just two months. We can recommend Ms. Hinnen in every respect.
Very competent advice.
We sold two properties through Retronova AG in December 2019. The managing director, Mr. Robert Weideli, accompanied us throughout the entire sales process. Well-connected, Mr. Weideli is characterized by professionalism and efficiency. His ability to realize visions makes him a trustworthy business partner who has been successful in the real estate industry for nearly a decade. Absolutely recommended!
