We had a wonderful time in Vienna in Mortiz's place :)
Our plane was cancelled so our arrival was delayed and Mortiz was really quick to react and manage everything for our arrival.
The flat is great. Spacious, clean, bright, and the balcony is cosy and very quiet. Is it situated in a nice area, close to the subway so you can reach the city center easily.
We recommand this place to all who want to spend few days in this great city !
