A very cheerful hostel, and in general an excellent network in Europe, I was in France, Amsterdam, and here. Walking distance to Alexanderplatz, a pleasant bar on the ground floor.
A great place to spend the night, near Alexanderplatz, 10 minutes walk to the main tourist spots. In the rooms, each bed is enclosed with a curtain, which creates an individual space. The staff is polite, friendly and ready to help. Everything is clean and unexpectedly quiet at night.
