A nice room really close to the Ubahn, with convenient changes for visiting Berlin (get in the 7, then the 8, you are at AlexanderPlatz). The journey takes around 30 min though. Elnaz Mother is a lovely person, we loved the cat as well <3
I guess it is not a place for people who aren't into cats at all. For people who are, it is great^^ The coffee is good, you can get tea although the kettle is not in the room.
