We found the apartment to be exactly as described. It was clean, comfortable, well-supplied (it even had a universal plug converter, umbrellas, and other stuff like that). It's pretty close to the train from the airport at Stazione Ostiense (31 minutes!) and the Piramide subway stop (as well as busses to take you anywhere). Testaccio is the culinary heart of the city, so there's lots to choose from by way of Roman cuisine. It's also an easy walk from the heart of things (like the Aventine, the Foro Boario, and Ghetto).
