Andrea's space is centrally located to a lot of great restaurants, cafes and shops. You are a few mins walk to the Ubahn and other tourists attractions. Despite being close, the place is on a quite street, so you don't hear much.
You are on the top floor (there is a lift) and have a nice view of the street below from the living room. The space has the basic kitchen needs for your stay. When we were there, it was quite hot and the space can be hotter inside than outside, there are some fans to help keep you cool (small one and a large industrial fan-a bit noisy can't use it to sleep). Overall, great location for Vienna.
