I was surprised how nice this hostel was. Staff was very polite, friendly and helpfull. Everything was nice and clean and breakfast was really nice for 5€. Only thing is that you can hear people walking on a floor above pretty loud, but it was fine beacause most of the people there went to sleep early. If you are really light sleaper, you can even purchase earplugs in the vending machine in the lobby :D Location was nice in a quiet, residental neighborhood and only 15-20min walk to the main square. I will probably stay there if I ever visit Berlin again!
