We commissioned the company Onesta Simon Leu in 2023 to sell our modern 5.5-room apartment and were very satisfied from the very beginning. Already during the first conversation, the company made an extremely serious, competent, and trustworthy impression. Throughout the entire sales process, we were always well taken care of and regularly informed about the current status. The communication was always open, transparent, and straightforward, so we were always well-informed. The sale of our property ultimately proceeded to our complete satisfaction. We sincerely thank you for the professional support, great commitment, and pleasant collaboration. We can wholeheartedly recommend this real estate company and would work with them again at any time!




The experience with Mr. Yves was excellent. He knows where to lead you so that you can make the best decisions and options. He looks for suitable solutions. You are in good hands with him.




Mr. Strasser is competent, very friendly, accommodating, and reliable. All wishes were fulfilled, and even after the purchase, Mr. Strasser was still helpful. I can highly recommend Simba Immo. Thank you very much for your work and your commitment.




Miriam Krumm accompanied us from the evaluation to the signing of the preliminary contract, and everything went smoothly. She suggested a sales strategy that allowed us to increase the value of our property and sell it in less than five weeks. To this end, she organized a shoot with a professional photographer and created a very appealing presentation of our apartment. We fully delegated the viewings to her and could see her commitment to selling our apartment, as she addressed exactly the right interested parties. She had a sense for the strengths of our apartment and effectively highlighted them. We could rely on her professionalism and quick responsiveness as soon as we had even the smallest question. Everything went exactly according to the schedule we had set together with her. We recommend the services of Ms. Krumm and her agency due to their first-class service and professionalism.




I was very satisfied with Mr. Gavilan throughout the entire time. His service was always courteous, professional, and reliable. I especially appreciated his commitment and support in my particular situation. Thank you very much for the great collaboration!




I already had very high expectations of Jannis from talking to friends who recommended him to me. But mine was an exceptional experience! Jannis is very personable and highly professional in every way. He organised multiple viewings and second viewings in a very short period of time. He had sold our apartment (notarised contract of sale) six weeks after our introductory meeting! I cannot recommend him highly enough. Thank you so much Jannis!




The communication was extremely straightforward and the purchase went quickly and without delays. Ms. O'Neill coordinated everything promptly and we could rely on her with a clear conscience.




I can wholeheartedly recommend Ms. Nelly Olah. From the first conversation to the successful sale of my condominium, I felt excellently supported at all times. Ms. Olah worked extremely professionally, committed, reliably, and transparently. She was always reachable, answered all my questions competently, and regularly informed me about the current status. I particularly appreciated her honest advice, her pleasant and friendly manner, as well as her great commitment during the sales negotiations. Thanks to her experience and dedication, my apartment was successfully sold at a very good price. I sincerely thank her for the excellent collaboration and wish Ms. Olah continued success. I will recommend her at any time with full conviction.
