It is located in strategic place. Near Metro/bus station, and you can walk to Colosseum. There is no signboard around the hostel so you should always keep in contact with the host (make sure you have cellular/internet connection). The host is always trying to reach us on our late night check in, we had some difficulties on our check in because we didn't have any cellular/internet connection and we checked in so late (2 AM, because we arrived at airport at 1 AM-we informed the host before). He also pay so much attention to guest's comfort. Host asked us to go into hotel and our room as quiet as possible in order not to disturb other guests. We got only 1 set of keys per group, not 1 per person.
