For sure would recommend this place to anybody visiting Vienna. Nice location, very clean and nice apartment which is close to everything. 3 tram lines plus one U-Bahn line are very close by, as well as all local shops you may need (Billa, Hofer, Bio-Markt, DM, Post office...). On top of that, Petra is easy and nice to communicate with, and will make sure your stay turns out to be better than you've expected!
