Alessandro's apartment was great. We spent a week there. The location in Rome is perfect: you are in the middle of everything, steps from the Vatican, Castel Sant Angelo etc, but at the same time the street is very quiet (which can be good to sleep, most Rome's streets being pretty noisy during weekends).
The apartment looks exactly like pictured - if you are very tall (1.85m or above), it may not be for you as the top floor has a low ceiling and the bed is 190cm long. But anyone smaller than that should be fine. It was great for us. The AC worked great, the water was warm and worked great as well. The bed and sofa were really comfortable. Not a lot of light in the apartment, but it is actually great during summer as it keeps it cool.
Communication was excellent and the check-in/check out was made super easy by our host.
