Great place, nice and communicative staff. The prices are affordable, the rooms are small but cozy and clean. The atmosphere of the hostel is really friendly. The location is excellent, relatively close to Alexanderplaz (I didn't have heavy luggage, so I walked), and you can also walk around the central part of the city. I can't say anything about public transport, because I didn't use it. The bar is open at night, it was a little noisy in the room, but it did not interfere with sleep. It was very pleasant for me to stay there!
