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






We sold our property through Peter and Nadine and are completely convinced by the entire process. From the first conversation to the final transfer, everything went smoothly. The many valuable tips and the expertise that was provided to us throughout the entire process were particularly helpful. We took advantage of the complete service and therefore did not have to worry about viewings or organizational tasks. Everything was handled reliably, transparently, and with great commitment. You can feel that Peter and Nadine work with a lot of passion, professionalism, and genuine enthusiasm. We felt well taken care of at all times and can wholeheartedly recommend both of them.



An exceptionally positive experience with Cyril Dux and Immodux – highly recommended! I would like to take this opportunity to express my extraordinary appreciation and heartfelt thanks to Mr. Cyril Dux and the company Immodux for the excellent support and successful mediation of my property in Kastanienbaum. Selling a property is not always just a business matter. Especially when it comes to a house that is associated with many personal memories and an important part of one’s life story, such a decision is also accompanied by significant emotions. This makes it all the more important to have a real estate professional by your side who not only possesses the necessary expertise and experience but also brings empathy, patience, a sense of responsibility, and a genuine interest in the concerns of their clients. I was able to experience exactly these qualities in Cyril Dux in a remarkable way. From the first contact to the successful completion of the sale, I felt I was in excellent hands with him. His professionalism, reliability, personal commitment, and always friendly and respectful manner left a lasting impression on me. What I particularly appreciate about Cyril is his ability to combine professional competence with human warmth. He does not view a real estate transaction merely as another business deal but takes the interests, wishes, and even the concerns of his clients seriously. Throughout the entire sales process, he demonstrated great commitment, foresight, perseverance, and remarkable responsibility. Even in challenging situations, he remained factual, constructive, and solution-oriented. His willingness to personally engage and see the matter through to a successful conclusion




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.






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.



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!




We had the pleasure of working with Mr. Frank Meierhofer on the sale of our new construction project in Bülach. He sold the duplex family home extremely professionally and efficiently. We particularly appreciated his clear communication, reliability, and experience in real estate sales. Thanks to his great commitment, the houses were successfully placed in a short time. We felt well advised and supported throughout the entire process. We are very happy to recommend Mr. Meierhofer and look forward to future collaboration.
