What I liked: Rainer is nice and helpful. Apartment is in the very very center, and authentic. Flatmates are nice. Room has enough space and is clean enough.

What I personally liked a little bit less (but this all depends on your preferences and expectations): this is a house with several people living in it, and functions and looks like a student house. Of course this can be totally fine, but was not what I was looking for. I probably did not check well enough the review comments when I made the selection. The room is somewhat basic. Internet connections a little bit weak. And the rest of the apartment a little chaotic. Again: this can be fine, and all depends on your preferences and so on.
