Helpful & chill staff; great location, super quiet sorrounded by green areas, walking distance from supermarkets, public transports and city center (Alexanderplatz).
Room 214, just needs some improvements on the lighting system: when you share a room with 4 people lamps are kind of important and that woodbox + lamp + power socket system shown in the photos should be available at this room as well.
Other than that, great stay. 11 nights might be my personal record at an european hostel! "Prost" to that!
