We loved Vienna and we loved Stefan’s apartment. We had a little problem when we arrived and Stefan was there quickly to solve it. The apartment is in the best location, in the main street of the center of Vienna, the best bars and stores, and a few steps of the historical locations.
The subway is just one block to the apartment and it was so easy to connect to the different places and the train to go to the airport. Vienna is definitely more charming if you rent this apartment.
