We stayed here for 4 days. Actually we were worried about what we had made right choice after booking. If everything in here was bad, we would have felt like ruined. However, once we arrived here, we didn't have to worry. Their service was perfect, staffs were friendly, and room was also clean. So we could sleep, take a rest quite well. Location is also not bad. Termini station, Coloseum is within walking distance. Trevi fountain is 20min away from here on foot. One thing negative thing is "Wi-fi" I don't know other rooms about that. But our room's wifi connection is not strong. So we'd rather use data.
I think "Relais Forus Inn" has a reasonable price. I think you'll have nice experience here.
