Tina's apartment is really nice and modern. It is very close to the subway station and just 2 stations from the city centre (if you want to walk it takes approx. 25min). Very silent area, so nothing will disturb your sleep.
Tina is very friendly and hospitable, she gave very good recommendations during my stay and provided some maps, that I could borrow. I had very nice and interesting conversations with here. I can highly recommend to stay at Tina's apartment.
