My boyfriend and I stayed at Maurilio's place for 3 nights (Friday, Saturday and Sunday). Maurilio was very friendly and welcoming. He gave us a quick tour of the apartment and then let us be and gave us our privacy. We were out and about the city for most part of the day and only came back to the room to shower and sleep.
Just be aware there is no elevator. Be ready to carry your luggage up 3 flights of stairs which is not so bad if your luggage is not too heavy.
Location is in the great neighborhood of Trastevere. Amazing! The nightlife is great here. It is centrally located and is only a 20 to 30 min walk to most of Romes main sites. Plenty of bars, cafes and restaurants; with that said, it gets very noisy at night! There is a restaurant in the first floor of the apartment location and at night (after midnight) you can hear the loud breaking of glass from them cleaning up. Early in the morning the street sweeper goes by and that may wake you up.
The apartment is kept very clean. We used Maurilio's kitchen to have breakfast every morning. He gives access to the kitchen until 11 am. We would definitely come back here if we were to visit Rome again!
