The collaboration with Quartett Immobilien and Ms. Gojani is always courteous and efficient. I greatly appreciate this!

















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.
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.
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.
Through the open and honest communication from Lukas Flück, I was convinced from the very beginning that I could sell my house at a fair price. Thanks to his competence and commitment, Lukas was able to find the right buyer within a few months, and the achieved sale price was above my expectations. I can wholeheartedly recommend Lukas Flück and would work with him again at any time.
We got to know Mr. Demir as a warm, friendly, and very accommodating person. He impressed us with his good market knowledge and competence during our first meeting. It was a very easy decision for us to go the route of selling our former apartment with him. The perfect sales exposé, the consistently competent support, the communication up to the efficient conclusion at the notary were simply exemplary. Having such a broker for the management of such a transaction is simply desirable. We hold Mr. Demir in high regard and can recommend him with the best conscience and much joy.
