This was a fantastic trip. Francesco met us at the bus station nearest the apartment (and helped us with bus directions) then walked us to the flat. The room is the size of a normal American hotel room, which is bigger than a normal hotel room in Rome. Furnishings were simple and clean, with a small stove, fridge and sink.
The bathroom is small (also normal for Rome). The only downside to the flat is the hot water for the shower. If two people plan to shower within the same hour, make them quick.
The location is great. No more than a 25 minute walk from all the major attractions, including Vatican City. Also, it is very quiet inside, no street noise at all.
I strongly recommend this flat. Thanks, Francesco!
