Everything, from the location near the piazza del popolo, to the communication with the hosts was very nice! The check-in was uncomplicated, the hosts explained everything and took their time. The location of the Air BnB is one of the best you can get in rome, maybe a bit loud at night due to the busy traffic so you can’t really sleep with windows open, but every main attraction is walkable in 15-20 minutes! Metro, bus stations and many e-scooters are also easily reachable within 3 minutes. Would highly recommend!
