Our train was delayed so we arrived to Vienna at midnight, but Nora and Andrej was kind enough to wait for us and to show us the place. The apartment is very close to the center station but also quiet at night. It's very bright, being on the 3rd floor with 3 windows and is equipped with everything needed for a short stay. The communication was throughout, Nora explained to us clearly how to arrive to the place and she usually replied fast.
