The BnB is in a convenient location, a short walk to the metro which is only 2 stops from Termini, so it's easy to get to wherever you need to go. There are cafes, good restaurants and a nice park all within walking distance.
The room was clean, nicely decorated, and the host is very nice. My only complaint is that the higher part of the wall between you and your neighbor's bathroom is glass and you can hear everything (literally) from each other's bathrooms, almost as if they're in your room. That made things a little uncomfortable.
