Great holiday! Nadia's appartment has everything you need for short or long stay in Vienna. It's very clean and comfortable, even for families with children. Everything was as described.
It's not in the city center but is in quiet district with easy access to the city center. Several transport lines (U-bahn, tram and autobus) stop in 2-3 minutes from the appartment. We usually used tram No 2 that brings you to Schwedenplatz in 10-15 minutes (where you can find delicious ice-cream). It goes along Burgring so you can reach all main tourist attractions with this tram.
Nadia was very kind to help us to find parking. She is very easy to communicate.
I would recommend Nadia as a great host. We will definitely return!
