Carolines place is in a wonderful location, near public transport. The apartment is very large, the kitchen has everything you need, and the was clean. The bathroom is tiny BUT I wasn't in Berlin to spend a lot of time there.
A lovely touch was the two bikes they have available - we cruised through Berlin on two separate dates. In addition She left a nice list with tips for the area. She was always responsive and flexible with check in.
I would stay again!
