The location is very good - there are many shops and possibilities nearby, you are also very fast in the city center and the famous Schonbrunn is 15min.by feet.
The flat is nice, good for a short-term stay for a single person or a couple that doesn't mind noise and light from the street.
I would recommend to buy a blackout curtains and change the bed though, because it makes so much noise when sleeping on it :) for me it was very hard to sleep well there.
