Mr. Marcel Bieri accompanied me very professionally throughout the entire sales process. His assessments were understandable, realistic, and well-founded. I particularly appreciated his calm, structured manner as well as the open and direct exchange. Communication worked flawlessly – feedback was timely and reliable. I felt well informed and taken seriously at all times. Mr. Bieri brings a lot of experience in the real estate market and knows what is important for a successful sale. I can recommend Marcel Bieri from Della Valle AG with a clear conscience.
Ms. Tröndle was recommended to us by a relative who knew her through business connections as a second opinion, since we already had an offer for the sale of the apartment at that time. Ms. Tröndle made her first visit in April 2025, and it was immediately clear to us that we would proceed with her for the further process. Crucial was that she took our concern about finding a suitable apartment after the sale seriously and offered us her assistance, unlike the competitor. She implemented this immediately, and we were able to rent an apartment for June 2026 through her mediation as early as July 2025, even though the marketing of our apartment only took place in the fall. This was a great relief for us and meant even more trust in Ms. Tröndle. During the sales process, Ms. Tröndle always provided us with good advice and support with her suggestions and recommendations. The sale of the apartment was a great success, and we are very satisfied with it. We are happy to recommend Ms. Tröndle due to her high level of expertise, reliability, and friendliness.
Due to my upcoming retirement, I decided to reconsider my situation/living circumstances. I no longer needed the large 5.5-room apartment spread over two floors in the foreseeable future. The decision to sell the apartment was soon made. The search for a realtor took a bit more time. There were realtors whose offers were economically more favorable, but Dalyan Yorulmaz received the assignment because he convinced me as a person. The apartment was already reserved after a short listing. The sale and the formalities were handled to my satisfaction; I can recommend Dalyan Yorulmaz from my own experience.
Swiss Real Estate or Marco contacted us and offered his services. At first, we were a bit uncertain and skeptical, but through a personal meeting, he gave us security and trust. He helped us find a suitable tenant for our beautiful apartment. Throughout the process, he was always very professional, always available, and carefully reviewed all documents. He accompanied us throughout the entire process – all the way to the handover of the apartment, including cleaning with a guarantee acceptance. I can wholeheartedly recommend him. His transparency and commitment were his greatest strengths.
Valuable support already in the decision-making and preparation phase. Pragmatic and straightforward collaboration throughout the entire sales process, and also various, sometimes unpleasant and thankless tasks were taken on without additional costs. Very good price-performance ratio. Also highly appreciated by the buyers due to his courteous and professional manner.
Mr. Zika has very competently accompanied us, focusing on our needs before, during, and after the purchase, tracking and processing the necessary steps at all times. Thank you very much and highly recommended.
Mr. Milanovic accompanied us perfectly during the purchase of the apartment. He responded to questions in no time at all. When it came to finding appointments, he was always very flexible and also actively supported us with dealings at the authorities. All in all, my wife and I were very satisfied with his work and grateful for his great support.
Outstanding service and quick sale! I am absolutely thrilled with the collaboration with Mr. Höhn. Mr. Höhn conducted a highly professional property valuation and created a great exposé. Thanks to the excellent effort, the property was sold very quickly. I can highly recommend Mr. Höhn!
Competent, quick, flexible, and professional. I had very good experiences with the sale of my property. The support was competent, professional, and always flexible. Everything was handled promptly and reliably. I would choose this support again at any time and can recommend it without reservation.
