our stay at NoHipster hostel was somewhat unpleasant, although there were aspects of these accommodations that were decent.
the hostel space, including our bedroom, was pretty dirty (dust in the bedroom, mold on the shower door, overflowing trash). in addition, the location was an hour walk from the city center which was longer than we were expecting.
that being said, the hosts were kind and gave us suggestions of how to spend our time in rome after we arrived. the other guests in the hostel were friendly and the location was good for hip nightlife (although we came in january and the scene was pretty quiet).
overall, if you're looking for cleanliness, comfort, and a spot close to the city center, i would not necessarily recommend this hostel. our experience was not horrible, but a let-down nonetheless.
