Myself and two friends stayed at Ali's place for a three night meet-up in Vienna and it was exactly what we needed. Extremely convenient to get to from the airport with a direct (20minute) train running the majority of the day. Also very easy to get into the center of town with the tram or train. Spacious place for a short stay and excellent value for money. The hosts were extremely quick to respond to questions and were very accommodating and understanding when we incorrectly followed the checkout procedures. Would definitely recommend!
