What a great location to stay while in Vienna! I could see Vienna University as well as the Danube tower from my window and the roof terrace, which is very nice.
Being 2 minutes from a metro station and also from restaurants, cafes, grocery stores is great, at the same time, i was far enough from city centre so that it is very quiet. The apartment was very bright and tidy. It is very basic though and so best for one person only and short stays but quite enjoyable overall.
