The apartment is super clean and nice. I stayed two weeks and it felt like home. Especially the bed is so comfy! I would really recommend it and will definitely book it again for my next visit in Vienna. The location is also awesome, only a 1min walk to the tram station and from there only 15min to Schottentor, if you want to explore the inner city. There are several supermarkets nearby and also some nice restaurants and coffee places down on Währinger Straße. As a woman traveling alone I felt totally safe in the area, it's very quiet and peaceful.
The communication with Xiaoyong was also super easy!
