A big thanks to Giuseppe, our really easy host (we were 4 and we did not all arrive and leave at the same time; but it was ok 4 him. we arrange well to get the keys etc). The flat is really nice and well equipped (and clean). The location in the Monti barrio is great if you want to be close to the Colisseum and not with too many tourists.
We had a wonderful stay thanks to him.
