We stayed in Mattia's flat for 4 nights with our 3 teenage children, there was plenty of space for all of us. The flat is extremely well located - 20 mins walk to the Colosseum and only 8 mins to walk recommended local Trattoria. The supermarket is 3 mins away and the building is lovely and in such a nice area. The Aircon in the bedrooms is very welcome although it would be great to have it in the lounge/dinner area also. Wi-fi is very good in the central area of the flat but doesn't reach to all of the bedrooms.
