This place is located closer to Piazza Berberini than the Trevi which is BETTER than we expected; on a side street which avoids a lot of heavy tourist foottraffic and close to taxi and underground station. Very close walk to Spanish steps.
The home is very clean and stocked with plenty of towels and basic kitchen things. There is plenty of room. We were a group of three adults and three children. The only obstacle is that the elevator does not go all the way to the ground floor (there is still a set of stairs upon entry and exit) which was difficult for the stroller. Otherwise, no issues. Super safe. We would definitely stay here again.
Our favorite restaurant in Rome is located at the end of the street; Collene Emiliane - suggest you give it a try, you’ll need a reservation for either lunch or dinner. There is also Sofia just a short walk away and great boutiques between this location and Spanish Steps.
