Great place just meters away from the Colosseum (and its metro station). Very spacious. Andrea received us and was very helpful with advice about the city, transportation and everyday stuff; good host.
The dining area has double-height and it's framed by a huge wood bookcase. The kitchen is fully equipped. Heating was good. The only drawback: if you're tall (like my husband: 1.89m) then the shower will be a bit of a problem. His head touched the ceiling and the shower head was just above his chin. I think if you're below 1.85m you won't have this problem (my husband didn't mind having to duck for a few minutes a day). Nevertheless, the bathrooms have ample room (it has a half-bathroom near the kitchen and a full bathroom near the bed).
Will stay there again when we return to Rome. Andrea was very welcoming, the apartment is big and in a very good location for moving around the city.
