We really enjoyed our stayed 7 nights stay here. Apartment was clean and very well equipped, beyond our expectations. In addition to the many little "extras" such as coffee and dish washer tablets, a couple of cell phones for internal calls in Austria were there for our use, and they proved to be very useful!
Apartment is pretty small, especially the shower area, however it is beautifully decorated in a modern style, and very well designed, so it didn't bother us.

Location is excellent. A subway U4 station is across the street. The city's center is a few stops from there, and in general Vienna's metro and public transportation is superb, so you can easily get everywhere in this lovely city from this station. There's even a U6 station a few further minutes walking distance.
There are at least 3 large supermarkets in a short walking distance, including a huge Interspar, and an excellent shopping street.
Nearby streets are clean, and beautifully painted and decorated, keeping the Vienna standard.

And above all Maida, Kemal's wife, was very nice and welcoming. When we arrived she spent time patiently explaining everything, and later helped us whenever we needed, and very quickly (The family lives in the same block). So thank you again!

Highly recommended.
