There were two of us on this trip, and we were very comfortable. The bedroom can fit 2 people comfortably, and the sofabed in the living room 2 more. So it'd have worked for 4 too. There was a laundry outside, and convenient places to dry our clothes. There we kitchen facilities too, which we didn't use. The flat is seconds away from a cute bookstore/cafe, and minutes away from a Metro A line that takes you most places you want to get to, including the Vatican. It's far enough away from the centre to be quite and peaceful, but near enough to a Metro line to be convenient. Perfect. Riccardo was a real gentleman too.
