We are very satisfied with the apartment. The place in general - the Donau Zentrum- is very interesting to live in, the park nearby is marvellous, and the most important is the view from the apartment - to die for:) a supermarket is just downstairs, subway station - in couple minutes walk distance (10 minutes and you are right in the center of Vienna).
Sladan is a welcoming host who tells everything you need or want to know.
Thank you, everything was really nice!
