Stayed in the apartment for 3 nights with my girlfriend.
It was a pleasure, the place is totaly renovated and fully equiped with every thing you need.
Vincent the co-host was very nice to us and gave us some great tips.
The location is not at the center of Vienna but the public transport is so good that it doesn't matter (the public tranport station - UBAN - is 2 minutes away by foot)
Great value for money! perfect for couples!
