We stayed for five nights and had a wonderful experience with Riccardo. From quick communication, to accommodating are arrival time that was outside of their check-in window, to him and his staff always being pleasant and cheerful, we had a wonderful time!
The MEA 'Red Line' is about a block from the front door of the building, and grocery stores (EmmePiu, Conad, COOP) are about a 10 minute walk; the Colosseum is about a 20 minute walk.
We'd definitely stay again!
