My stay in Paolo's apartment was perfect from all the points of view.
Paolo is such a very nice person and he was always available answering immediately at any question and request.
The apartment is exactly as it's illustrated, very clean and silent
(Paolo just changed the windows that cut any noise), the kitchen it's full of accessories and the Wi-fi run perfectly.
The apartment it's only 100 m from the mainline of the subway and achievable in 10 min walking from the station.
Colosseum it's very closed and the area it's full of good restaurants and markets.
I will certainly come back here next time in Rome.
