This is the flat we would like to have if we lived in Vienna! Super clean, extremely luminous, classy decoration, and a great terrasse with sofas above a tiny square with bars (the flat is located in a lively young district with many bars and restaurants) all of this at less than a 5-minute walk from the historic center. The only downside is the possible noise and light from the street if you use the beds in the huge living room on the Operngasse side. But there are 2 bedrooms (a tiny one and a great one) with efficient curtains on the other street side which is quiet. The kitchen is well equipped as well as the bathroom (with a real bath) and there is even an iron and iron table!
Michael is a great host who personally welcomed us and explained everything about the flat and its surroundings (restaurants etc), attention is given to every detail, complimentary sweets and beverages (including a nice bottle of wine) and top of the top in a little frame in the living room a photo of my wife and me (from our Airbnb profile) for a warm welcome!
We definitely recommend the place and would be happy to come back!
