Massive place that is centrally located, just steps from St. Stephans. Huge living room with smart TV. One bathroom with shower and toilet. One bathroom with a bathtub and sink. Second bedroom is in between living room and half bath.
Key pickup was at a hotel a short drive away, but not an issue for us, as it was enroute from the train station.
All in all a very nice stay and felt right at home in Vienna.
