Great location on a one-way street close to the Colosseum & Forum, transit and neighborhood restaurants. Sleeps 2 in a giant bedroom with plenty of closet space and drawer space, another 2 could sleep in the smallish living room hide-a-bed, but it'd be cramped if all 4 were adults. Not much dining space if you plan to have any meals in the flat but a well appointed kitchen area for quick easy meals. The shower was tiny and the hot water did not last for the duration of one shower.
All in all we were generally happy with the stay and would return.
