The apartment is very well furnished and fit our group of 3 comfortably. Bedroom was ok, bathroom was spacious and had amenities at hand. Kitchen had most of the supplies we needed (the rest we could buy in one of the many supermarkets in a short walking distance). Location was also pleasant: right next to a metro station (only two stations to Stephansdom) and a short walk to the historical center.
Laundry is available but it is necessary to pay 4 euros per wash.
We had a great time in Vienna!
