We loved the location of Marzia’s apartment. It’s 1 mile (20 min walk) to Roma Termini (the main train station) and very convenient for using bus transportation to Colosseum, Trevi fountain, and Spanish steps. You can also walk to these locations as well if you are up for walking a few miles. We really enjoyed being close to the Borghese Villa as the park grounds make for excellent strolling during the day. The neighborhood was quiet and safe when we stayed there in late March 2019.
