I was accompanied by Edoardo Köppel and Köppel-Legal AG during the sale of my 2.5-room apartment on Rossweid in Sins and was very satisfied with the collaboration. The initial assessment of the apartment and the realistically achievable selling price was understandable, honest, and well-founded. The professional preparation of the sales documents and especially the successful photos made a very good impression. Throughout the entire sales process, Mr. Köppel was reliably reachable, responded quickly, and kept me informed transparently about viewings, feedback, and the next steps. I particularly appreciated his calm and solution-oriented approach with sometimes demanding interested parties, who initially backed out, later agreed again, or tried to significantly lower the price. Mr. Köppel conducted the negotiations consistently and with the necessary sensitivity. Despite these challenges, the apartment was sold at a higher price and without unnecessary complications. I felt well taken care of at all times and can recommend Edoardo Köppel and Köppel-Legal AG without reservation.
