My family of five stayed in Francesco's apartment for four nights.
The location is fantastic, right in the heart of Trastevere. There's plenty of restaurant's, bars, cafe's and gelato to choose from.
The apartment itself was more than big enough for the five of us and apart from a few issues to begin with we enjoyed our stay there.
Francesco was quick to respond to the issues we had and deal with them promptly.
I would recommend anyone coming to Rome to stay at Francesco's apartment.
