Perfect location - less than 5-minute simple walk from main train station. We were able to do a loop of all the main attractions starting and ending at the apartment. It's very safe; you're on a main well-lit street and you need 4 different keys to get into the actual apartment. It's on the 3rd floor (for American's - 2nd floor for Europeans), but there is a small elevator you can use to take suitcases up and down. As a pampered American I would have liked better air-conditioning (there's only one unit in one of the bedrooms). But after a couple hours, it brought the apartment temperature down enough to be generally comfortable. The host was wonderful, they let us check in early because the previous tenants checked out early and they cleaned immediately. And when we got there she provided us a map of Rome and told us how to go see all the sites. She was very nice and spoke plenty enough english. Great stay.
