Gerhard is an amazing host and a very nice person; he took care of all our requests both before and during our staying and made sure to cover all our needs.
The flat is wonderful, brand new, very well designed, fully equipped and very silent; it is in an old and completely renewed building in one of the best districts in Vienna (walking distance from the city center, lot of shops, cafes and restaurants nearby).
We are really looking forward to coming back!
