It was my second time in Wien, and thanks to this stylish apartment I could confirm to myself how interesting this city is. The room with out-of-tune piano was very comfortable and bright, as well as the kitchen were you can even meet one of the flatmates and have a pleasant conversation with. Another good aspect of this flat is definitely its position. Just 15min walking to the museum quarter, next to the tram 49 and sorrounded by markets and an internet point (The connection in the flat is good, but a place for printing the boarding pass or other documents can be useful for some tourists).
I wish you a good time in this flat!
