Location can't be better, there are two public transportation stops with in 5 minute walk that offer three ways (Ubahn, Bus and Tram) to go wherever someone would like.
The third option, in 5 minutes walk it is the famous Mariahilf Street, a pedestrian street full of places to shop and eat, for everybodies taste, in the sorroundings, some specialty restaurants. Finally at the end of the 25 minutes walk you may encouter Historic Center of Vienna and all the museums.
The appartment is not luxurious and its not in a fancy building, but it is confortable and has a good price/service relationship.
Two supermarkets are in two block distance, which is really convinient.
