I had a great time staying at Flo's place. His flat is well-located close to multiple bus lines and the U4 and U6 lines of the U-Bahn. The bedroom was very comfortable and even had a sectional to relax on, and there were thoughtful touches that made the space feel like home. Flo was a nice guy and super clear and responsive with communication. I would stay with Flo again for sure and highly recommend his place for anyone visiting Wien.
