The collaboration with Quartett Immobilien and Ms. Gojani is always courteous and efficient. I greatly appreciate this!
Ms. Macconi accompanied the sale of my apartment from start to finish in an extremely professional manner. The valuation of the property was realistic, the marketing was of high quality, and the communication was always transparent and timely. Particularly noteworthy are her commitment, her market knowledge, and her friendly demeanor. The sale was successfully and swiftly completed. Thank you for the excellent collaboration.
Christian Schweizer has been advising me for many years and has sold an apartment for me twice. I have had very good experiences. Mr. Schweizer is very pleasant, addressed my wishes, and efficiently found a suitable buyer with care and humanity. All contacts related to the sale with the bank and authorities were handled by him. I received professional advice for my own financial matters. I would reach out to him again at any time. Highly recommended.
Very friendly and competent. Great, as viewings can also be done in the evening and on weekends. Really very dedicated. Also always reachable via WhatsApp if you have a question.
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.
Super competent advice, support from A to Z characterized by honesty, reality, relevance, and respectful interaction, including my seller wishes. I am very grateful to Ms. Stadelmann for the excellently conducted house sale. I can only highly recommend S. Stadelmann Immobilien AG.
if someone can sell, then only Roberto - sure, experienced with so much patience and passion. The best decision to sell with Roberto. Always happy to do it again. THANK YOU!
After a thorough property analysis, the sales mandate could be signed with Mr. Demir at the beginning of April 2026. Within a month, the professional sales documentation was prepared, and the necessary documents for the sale were gathered, allowing the sales activities to take place at the beginning of May. Mr. Demir's calm and factual manner created great trust among potential buyers. The sales discussions were conducted discreetly and competently. The expertise and market knowledge, reliability, availability, etc., were highly appreciated by both the buyers and us as sellers. Thanks to Mr. Demir's great effort, the sale of the property could be notarized by the end of June 2025. We thank Mr. Demir for his commitment and wish him continued success.
