Silvia and Family's apartment is a good place to stay while in Vienna. It's close to the subway (5 mins walk), as well as places to eat and shop. Don't be put off by the entrance to the building (it's a little run down), but once you are up the stairs and into the apartment, it's pleasant and airy, with high ceilings and a little bit of old world feel. The facilities are good. It's a great apartment for a family. The main bedroom is large, and the second is a good place for the children.
We were very happy with the stay. Enjoy.
