Nice flat, very central, next to the airport and the city center at the same time, that's great!
However, the walls are paper thin so that every sound made in the flat is hearable. So if the aim of the trip is to travel, have fun in Vienna, that's the right place to stay and I really recommend it! Otherwise, have a think about it.
Nearly everything you need is in the flat.
Dominika is a really nice person, if you have the chance to have a chat with! She makes you feel at home !
