This flat is THE place to rent for your trip to Wien !
Super clean and tidy flat, all equipped.
Daniela and Vladimir answered all our questions, where there to welcome us, with pastries and orange juice for the breakfast. There is a great coffee machine, quantities of different teas. Even are provided umbrellas and bicycles.
The flat is about 10-15 minutes to several metro stations, and there are bus stops very near.
The italian restaurant they recommend is very good.
If you come from Meidling Station ( Where the bus 1187 from airport stops) you can take the bus #9 which stops very near the flat.

To summup : excellent place to stay, highly recommended.
