We enjoyed our stay at Sergio's home for 4 nights. All the amenities were great: clean and properly functioning washroom and kitchen spaces. We were given a very informational short orientation of Rome when we checked in and the well thought out Map of Rome with train and tram/bus connections in the living room was especially useful for us to plan our daily outings :)
Although a bit outside central Rome, the nearby supermarkets, convenience stores and transportation connections make the place a great location to stay.
Please note that there is an additional cost of 3.5EUR per person per night to be paid at the time of check in accordance to local regulations. The host has mentioned this already in the description.
