This Airbnb was really clean and nicely done. Wolfgang was very helpful and communicative and we had no problem getting in touch with him or checking in. He also gave us some great recommendations and tips on things to do during our stay. The only thing that I would mention is that walking around after dark in the area of the Airbnb as two young women was not great. Our flight arrived late, so we had to walk from the metro station to the Airbnb and were followed the entire way by two men. That said, just be aware of your surroundings. Other than that, our stay was great and the Airbnb was conveniently located near lots of different metro and tram lines which made getting around Vienna easy.
