Daniela was super helpful and informative and kind. We were able to check in a bit early and check out a bit late which helped a lot with our schedule. The apartment has everything and is close to stores and restaurants and cash machines. The metro station is half a block, and it's also an easy walk to Termini, the main train station, where there are fast trains to FCO airport, direct buses to CIA airport (the one I used was on the south side of Termini station a couple blocks down from the metro entrance), and free covid tests (starting at 8 AM near the metro entrance). It's a 20-minute walk to the Colosseum and some more minutes walking from there to many of the other main sights.
