Had a great stay at Hanna's place. Was very grateful she was able to welcome me so late (flight arrived 21.10). The flat has everything you need to feel comfortable and is in a truly fantastic location - close to sights, both shops and Naschmarkt, public transport. Thanks to Hanna's help, I took the bus and tram to my course which was more fun than the U-Bahn I would otherwise have taken.
Bed is a futon and is a little hard, so if you prefer a softer mattress maybe not for you - it was fine for me.
Window looks onto courtyard and if people come in/go out at night, the light goes on and off, which can wake you up if you're sensitive to that.
Overall, highly recommended :)
