Rossella is extremely responsive. Her place is close to the Metro and it became our preferred method of travel (when we decided not to walk and take in the scenes). The apartment is straight down Manzoni from the Colloseum and there is a great grocery store, Emme Pui, to pick up kitchen snacks and supplies. Thought it is close to the Colloseum, it is in a neighborhood so you can get off the touristy path as well if you wish.
