Massimo was a perfect host, and his hospitality definitely had a great part in our great, week - long Rome experience. His place is everything as described, easy to access from Flumicino airport and the city center. We haven't used the public transportation, since we like to walk, and Trastevere is wonderful neighbourhood to explore and yet close to the most historical locations but also some new, hip parts of Rome (like Ostiense). The best tiramisu in the City (and beyond ) is also very close to Massimo's place :)
Massimo gave us number of local tips (sightseeing, food wise, etc) that proved to be valuable for our complete Roma experience.
