Mr. Ackermann excellently guided me as a buyer through the purchasing process with his expertise. We were able to complete the purchase on time and in close mutual communication. He is very passionate, always available, and knows the subject matter very well. I always look forward to working with passionate, experienced professionals who possess specialized knowledge. I greatly appreciated the collaboration and support from Mr. Ackermann. Happy to do it again.




The support from Qendresa Tosuni was excellent from A to Z. She provides exemplary assistance to both sellers and buyers. She was always available for questions. She is very competent, friendly, and helpful. I can recommend her 100 percent.








We found our dream home through Willi Immobilien – and were excellently supported from start to finish. A special thanks goes to Ms. Verna and Mr. Ackermann, who accompanied us with great commitment, expertise, and patience. Our concerns and inquiries were always answered quickly, thoroughly, and understandably. We felt taken seriously at all times and very well cared for. Thanks to their support, the entire purchasing process went smoothly and confidently. We are overjoyed and can highly recommend the team at Willi Immobilien!




Competent and straightforward real estate agent. Acts in the interest of both parties. The advice is comprehensive and leads to good solutions.








We were very satisfied with Ms. von Ostheim. Very friendly, competent, and efficient handling.








From the first conversation to the notarial certification, I felt excellently supported at all times. My real estate agent dedicated herself with exceptional commitment, great expertise, and a lot of passion to the sale of my apartment. I was particularly impressed by her transparent communication, the realistic assessment of the market, and her tireless efforts to find the best solution for all parties involved. I never felt like just a number – rather, I was personally accompanied, competently advised, and promptly informed about every step. Thanks to her professional marketing, her negotiation skills, and her great commitment, my apartment was successfully sold. Especially during a personally challenging phase of my life, it was reassuring to have such a reliable and trustworthy partner by my side. I can recommend her without reservation and sincerely thank her for her extraordinary efforts. Anyone looking for a dedicated, honest, and competent real estate agent is in the best hands with her.




We had excellent experiences with Philipp Niedermann from start to finish and can wholeheartedly recommend him. From our very first meeting, we were convinced by his open, authentic, and exceptionally likeable manner. He is not just a broker doing his job, but a person who genuinely cares about his clients. We particularly appreciated his patience and the ease with which he addressed our many questions. We were anything but experienced in the real estate market and had many questions—probably even some that are completely obvious to a professional. However, Philipp never made us feel like we should already know something. On the contrary: he took the time to explain everything clearly, listened attentively, and consistently followed up with us. We felt taken seriously and well-supported at all times, without ever feeling pressured to make a decision. His honest, straightforward, and human approach made the entire process incredibly pleasant. And there was never a shortage of humor! Dear Philipp, thank you very much for your time, your patience, and your wonderful manner. We greatly appreciated our encounters with you and would reach out to you again at any time. An unreserved recommendation!
