His professionalism, transparency, and exceptional commitment made the entire sales process significantly easier for us. Mr. Kielholz communicates clearly, reliably, and always on an equal footing. We were particularly impressed by his expertise in the Swiss real estate market as well as his ability to support both buyers and sellers in the best possible way. Thanks to his thorough preparation, his network, and his negotiation skills, we were able to sell our property not only quickly but also at an excellent price. We felt well advised and personally cared for at all times. We can wholeheartedly recommend Roger Kielholz as a real estate agent and would work with him again at any time."
He is efficient and factual. Responds quickly and is always reachable. For buyers-sellers between the ages of 20 to 50, he is the right contact person. In customer contact, he is always friendly and helpful.
Marc and Nadine provided us with excellent support in selling our house. From listing to contract signing, 1A customer service and guidance. Realistic, open, and above all, human. We can only recommend Marc and Nadine to anyone looking to buy or sell a house or an apartment. Keep it up, you two, it couldn't be better. Thank you once again from the heart.
We can recommend Mr. Trachsel and Mr. Külhan, both professionally and personally. We would have liked to provide our own photos for the sales dossier, or to receive more options from you. We thank you for your support.
Mr. Müller has convinced us with his calm yet goal-oriented manner. Professional, straightforward, and competent, he handled the sale. Mr. Müller is always reachable and very service-oriented. We would recommend him at any time.
Top service throughout the entire sales process. We were continuously informed about the new status. Appointments were kept and carried out. The communication was always clear and understandable. Our needs were taken seriously. Christian Vetsch has a pleasant manner with clients. The documentation online and on paper was detailed and the property was well presented. The sale was carried out to our complete satisfaction. Thank you very much to Christian Vetsch.
Ms. Linder was friendly, committed, and competent; she took care of all our concerns/questions promptly. During the viewings, we always had enough time, and the handover went smoothly and harmoniously. We can recommend Ms. Linder at any time!
Mr. Carlo D'Angelo far exceeded our expectations. While we were still living in Cyprus and planning our move to Switzerland, he took care of everything on-site in Switzerland/Basel. He was always reachable, invested a lot of his personal time for us, and accompanied us throughout the entire process with great kindness and professionalism. He was even personally present during the key handover – anything but a given. Thanks to his commitment, reliability, and friendly persistence, we found our new home. Anyone looking for a realtor they can truly rely on is in the right place with Carlo D'Angelo. We wish you continued success in your work and God's blessings! Lana & Andi
