Hase and O.

The place has a great location, is kept reasonably clean all day long, and has a couple of very friendly and helpful staff. Rooms and facilities are about average. What ruined the experience a bit was the constant unnecessary noise almost around the clock, weirdly and mostly caused by the numerous volunteers and long time residence there, with permanent talking, yelling, singing, music playing, excessive noisy cooking at all times of the day and night, showering in the middle of the night, loud working activities at unusual times and God knows what else. I have stayed in countless hostels over the last months, and am well aware that it can be noisy at times. But the noise here is simply senseless and unnecessary, and could be resolved with some clearer rules, some more care and respect for others by everyone staying there.
