My family visited Vienna for 3 days and I booked this apartment for them. The room was big enough for three people, and the location of the apartment is great - 3 minutes walk from the metro stop and therefore very well connected to the international bus station, airport and all the good sites in Vienna. There are also some great restaurants in the area, many supermarkets and a very good shopping street.
The apartment was warm and we used the kitchen for cooking in the evenings without any problems.
