The apartment was as advertised - comfortable, in a quiet location. The bedroom is comfortable, the same goes for the bathroom.
Cons - although the host was kind enough to provide ample instructions, I had some hard time opening the door. When he says pull & push it doesn't quite convey the struggle :)
The other problem is the lack of free parking space. As a tourist in Vienna I didn't know that there is no free parking in the city. If you park in front of the building you will get a fine. Ilya was kind enough to direct us toward a 24-hour parking spot that is located near-by where you can park for EUR 7 per 24 hours (if you can find a spot there).
The other thing that I would advice newcomers to Vienna is not to get rent-a-car in advance as I did - there is no point in doing so since there is plenty of companies and cars available at the airport and the taxes and insurances that you will incur could double.
Advice: Tram line 71 will take you directly to downtown - 6 stops.
