Dario's appartment was clean, quiet, spacious, comfortable and well equipped (hair dryer, kettle, cups etc).
It was close to the Coliseum (10 min walk).
Dario was very welcoming, he showed us good restaurants on the map, where to go out, and many other good advices for our stay in Roma.
Our flight was delayed (2 hours !), and we arrived late at night, but Dario waited for us, even if he had to get up early the next morning to go to work ! He was very kind.
Also Dario answers messages very quickly, which I really appreciated.
I would definitely recommand his place for a stay in Roma !
