Great little flat separate from the main house. The bedrooms are cosy, but even in the smaller one I had plenty of room for all my stuff. Stuff in the kitchen and bathroom was very clean and worked, and the location is great too — get the 27A bus just down the road to Kagran and you're on the U1 in 15mins. (Perfect if you're going to the Vienna International Centre, or into the centre for sightseeing.) There's plenty of shops nearby, and it generally felt like a nice area.
Pavel was very friendly and helpful, and he speaks great English. Can't think of anything more he could have done, really. Definitely recommend!
