Wolfgang is a delightful, interesting and very helpful host who was really responsive to our questions and needs. The apartment is very well located near two tram stops and a nice short walk/bike ride along the river into the Old City. Vienna is amazing and this is a fantastic place to explore from.
The apartment is roomy and adequately equipped. The bedroom did not get completely dark and sometimes got a bit cool at night, and the bed isa bit low. On the other hand, most other things in the apartment seemed designed for taller people, so the dining room chairs were a bit low for the table. There are lots of local shops and restaurants.
Overall, this is a good, reasonably priced apartment to see Vienna and enjoy a relaxing time.
