The location is perfect, close to the U6 subway. The street is busy with many cars going through, but it isn't disturbing at all, thanks for the good insulation. One of the bedclothes didn't seem clean, but it was hard to tell, apart from that everything was nice.
Pro suggestion: the parking in front of the building is very expensive (~2,5 euro/hour), and you can park only 1,5 hours at the time, and after you have to buy another ticket (and you can't do that via phone). So I chose the place called Garage Im U4 Center P+R, which is only 4 minutes by car and 15 minutes on foot from the accomodation, and you pay only 8 euros for 1 day in a guarded parking lot, amazing deal.
