The apartment is just ten minutes walking to Stephanplatz, the Vienna city center. However the 'flat' is just a room with bathroom ensuite, nothing else and the 'kitchen' is hidden in a box which is not, of course, a real one. We had to wait until 3.30 pm to get into the apartment, so we lost almost the day waiting for a key. Oh! Also, ee shared the apartment because there is another room. Nobody told us.
