I stayed for a night during a spontaneous trip to Rome and had a good experience : the place was clean o got a key to lock the bed/storage space. The reception is 24/7 so i was able to check in at a time that was convenient for me ; the staff was very friendly and helpful and the hostel was easy to find. I didn't feel unsafe in the neighborhood either (travellingby myself and i was quote anxious as people mention that the neighborhood around Roma Termini can feel quite unsafe, i didn't experience that but maybe it's due to the fact that i rented a Dott to get there).
