Maurilio's place is truly in the heart of Trastevere.
The room I had was simple but pleasant with a nice big window. The bathroom, which is shared with one other room, was very clean and I never ran into the other guests.
I liked being able to step out the door into the lively streets of the neighborhood, and then return to a truly quiet place for sleeping. I like that the wifi is turned off from I think 2 a.m. to 7 a.m., or something like that, as it really does affect sleep.
All in all a nice spot in Trastevere!
