Susanne's apartment was a great base for our stay in Vienna. The location is quiet but within walking distance of all amenities and the metro entrance is just 50 yards from the door, with the U3 line taking you to the main city attractions in a few minutes.
The very large airy living room and high ceilings make give the apartment a wonderful sense of space and all the bedrooms are of good size. We weren't troubled at all by the main bathroom location being off one bedroom as there's a toilet with a basin right by the entrance.
Susanne gave us all we needed and was very flexible on checkout time. No complaints - a great airbnb experience.
