Hostel located in the city center everything is at hand Halal snack shops, Berlin mall, metro ... All what. I loved the breakfast, part of which was halal and respected the diversity of religions. For the check out and breakfast is possible to shift to 11h or 12
Good hostel, there are restaurants, market, metro stations, shopping around, few minutes walking.
From my point of view, just the bathroom I didn't like, it wasn't dirty but the smell was not good.
Our stay at City Hostel Berlin was really good, the staff was nice to us, and helped us to add a night to our reservation. The room was clean, so was the bathroom. The location was also perfect.
The hostel is quite modern inside even if outside it does not necessarily give envy, the staff is very nice, the rooms are big enough (no air conditioning unfortunately ...), the bathroom is small but functional, the beds are comfortable even if they are low-end of appearance.
