We stayed at Alessandro's place for 2 nights with 2 of my friends. We were in the room for 3 people. I don't recommend this room (for 3 people) because it's really noisy, we couldn't sleep at all and it's cold. About the location, it's ok but it's not really close to the center, we always had to walk 15 min and then take a tram for 20 min and walk again. As for the price per night, I think it's reasonable. I was really disappointed by the host attitude, he barely told us how to get around with the transports, but he didn't tell us what to visit, when to go (per example, what is closed on sunday), that the trevi fountain was closed for reparation…We saw him once in the 3 days and he didn't ask us how the stay was. So, it's really not my best stay, sorry...
