We had a good time in Ingela's Flat. At first glance the building looks bad, but when you enter in the flat then it's another story. It's renovated, new furniture and well organized. Ingela prepared everything for the guests, even a guide for "dummy" of the area. One more thing, the position of the flat is perfect, 2 min from the underground: if you go with car keep in mind that parking it's not free during the week, but Ingela suggested us a P+R parking for 3€/day (it's 6:7 U-bahn stops from the flat). If you plan to visit Vienna, I would suggest to check if Ingela has a Flat free for you.
