Michael and Mathias were the best Airbnb hosts I have ever had! Their communication response time was incredibly immediate, kind, and patient. I felt so safe and relaxed. The tall windows in the flat make it wonderfully full of light all day. Towels and bedclothes were great quality. The University neighborhood has a fantastic vibe, full of stylish outdoor cafes and interesting shops. The flat is just a short 15-min walk to the "center" of town for Vienna tourist hallmarks - Demel, Sacher Hotel, Spanish Riding School, upscale shopping.... I will be back!
