its a good place right next to Termini, very clean and Salvatore is a nice, attentive guy. the building is pretty old, which led to some issues with water pressure during the recent emergency, where water pressure was reduced across Rome. Salvatore was on it w the water company and it was resolved in a few hours. also the neighborhood -- i dont think its really that dangerous, but one afternoon there were about two dozen carabinieri near the entrance, interrogating a few people. they didnt want to let me into the place at first, though they relented quick when i indicated i was staying there. if stuff like that -- none of it really serious -- doesnt bother you then its a great base for exploring Rome
