Thanks to Jovanna for a great host! We really enjoyed our stay during new year hollidays. The locations is great: 2 min by foot from Vienna's subway and 20-25 min by foot from the city center. The apartment is clean, comfortable and well-equiped with stuff you need to stay. Jovana's relatives were extremely friendly, they are living at the next floor and they will always help you with any probles (we borrowed some salt and oil for salat at 23:00, shops had been already closed). As a plus, Jovana's aunt speaks Russian a little. :)
I will recomend my friends to stay here, and, hope I will stay here once moore. 3 days is not enought fo Vienna.:)
