Roberto's apartment is just as described, a large, clean place that is extremely well connected to public transportation. The metro is just at the door as well as a tram (#3) to Trastevere. The Colosseum is nearby. From the airport it is only about 45 minutes by public transport. The beds are very comfortable, great internet, wall safe, well-stocked kitchen, and Roberto is very helpful/responsive. The apartment is decorated by art from local artists. As others have commented, Rome is a big, noisy city where people aren't shy to use their horns and this apartment is on the first floor next to a very busy intersection. We used ear plugs and that worked fine for us.
