Definitely recommended! We had a wonderful stay at Claudia's apartment. It is very clean, spacious and still cozy. It is located at a courtyard, very silent (although one morning we heard builders working on another building in the courtyard). Good to know: there are 4 bedrooms, 2 big, 2 smaller. One of the bigger bedrooms is adjacent to another small bedroom and has less privacy. The kitchen is very comfortable. It was nice to have 2 bathrooms (one is large, the other a bit small). The location is perfect, close to tram and metro stops, in a nice lively area with lots of shops, super markets and restaurants/bars. We didn't meet Claudia in person (keys are in a key box), but communication was very quick and easy. We would like to visit Vienna again and if again in a group, Claudia's place is one to remember for sure :-)!
