We enjoyed our stay at Claudia's flat very much! The flat is more stylish than on the pictures and the living room is very spacious and light.
The flat is very close to one of the main tube stations (near the Prater) and it was easy to get to the centre of Vienna (it takes about 20min to walk as well). The apartment was clean and tidy, very warm as well (which was perfect in cold Vienna). Claudia was super quick in responding to any queries we had during our stay and she is very friendly. It was unfortunate that we had to check out early in the morning and had to leave our bags in a locker at the station, but she was nice to explain to us details about this and it costs 2 EURO, so not a real issue at all. We definitely recommend Claudia's flat for a short break in Vienna!
