The apartment was clean and perfectly comfortable for a couple for a few nights. It's actually their work studio some of the time which is cool - was full of architecture books which we enjoyed looking at. It's on the ground floor - with big windows (frosted) that look directly onto the street which not everyone may be comfortable with but is kind of cool and actually very useful if you have big suitcases. The apartment is located near the main station (20mins walk) which was very helpful. Overall would recommend it for any young couple looking for an inexpensive, quiet, clean place to stay in Vienna.
