Location, location, location. Valerio's place is positioned central to Termini, Cavour and Vittorio Emanuele metro stations which means you have easy access to nearly anywhere in Rome. However if you like to walk you can get down to the Colloseum and other highlights of the Centro Storico Rome quickly and easily. The apartment itself is up a few flights of stairs which can be a thigh burner after a long day of walking but otherwise the accommodation was superb. Valerio is very communicative and a great host. Within a street or two of the apartment there are supermarkets, bars, pizzerias...anything you'd really want. We stayed for 6 days and would have loved to stay longer. Can't recommend this highly enough.
