It is very recommended place to stay in Vienna located in convenience locations, many supermarkets nearby, within 5 min walk to tram (no. 18) and 10 min walk for train to airport.
Georg and Hanka (his co-host) were very great. Hanka waited us at bus stop and lead us a way to the room by herself.
The room decorated in modern style and has a lot of things you need for stay such as hi speed WIFI, Large TV, Apple TV, Kitchenwares, dishwasher, iron, washing machine, etc.
Georg & Hanka also gave us a fast response when we had some questions. If we have a chance to come back Vienna again. We definitely will stay here again.
