We stayed in this apartment for our 3 week stay in Vienna and it helped make our vacation a wonderful experience. It is in a terrific location, just blocks from the Ringstrasse and all of the main tourist sights. There is a tram that stops just a block away. The U6 UBahn (Thaliastrasse stop) is just up the street - just 2 stops to the Hautbahnhof main train station. Also, there is a variety of very good restaurants in the neighborhood including sushi, Vietnamese, Croatian and Persian plus, of course, a good brew house just next door.
The apartment is a comfortable one bedroom with a full kitchen. It is an easy one flight up and located in the back, overlooking a quiet garden. The landlady is very helpful and accommodating. I would recommend this apartment to a friend visiting this wonderful city.
