It's a nice apartment, with plenty of space for 4 people to stay comfortably. Everything was good there except the shower, which is so tiny that using it is a real struggle. Location is not great for most of the main Rome attractions - you have to use metro to get anywhere except the Vatican museums, and apartment is at least a 10 minutes walk away from the nearest station, with significant up-hill on the way back. But for these minor inconveniences, we all definitely enjoyed our stay at Mary's apartment.
