It's great.
The area is quiet.
Close to u-bahn, s-bahn, 100 and 200 "sightseeing" buses.
Apartment itself though small is comfortable.
Plenty of light. Everything is top-notch.
I especially enjoyed the attention to details:
Forgot your toothbrush? There is one.
Need clothes pressed before going out? There's an iron and a board.
Live tulips, complementary beer. It's great.
