A lovely, well-arranged flat in a convenient neighbourhood for the historic part of town, as well as the good restaurants. The flat was very clean and comfortable. Communication with Walter was very efficient; even though we didn't meet in person, Walter was very quick to respond to questions, and actually reminded me of a couple of things that I had forgotten, due to not having used air bnb for a long time.
I would definitely recommend this flat to single travellers or a couple. We walked into historic Vienna and back each day. The flat is excellent value for money, meaning there's more leftover for some famous Viennese cakes!
