Barbara’s place is in a great location. Although Campo de’ Fiori can get pretty raucous, the apartment is extremely quiet. Barbara is a super sweet lady and a great host and has arranged discounts at several of the restaurants around the square. Taxiing from both the train station and to the airport are extremely easy. Also, it’s pretty equidistant to both the Vatican and the Colosseum; we walked to all of the big attractions in Rome from the apartment in a day (10.5 mi/17 km round-trip), which can be made a little less taxing if broken into two days.
