*Very* conveniently located between Piazza Navona and Vatican, right in the center of Rome. You don't even need a bus or subway to go to most places from here. The street itself is quiet.
The place is very nice and great for up to 4 persons (a double bed and a bunk bed). There is a small kitchen, bathroom, I guess everything you need.
Alessandro picked us up when we came by bus and took us to the flat and explained all.
Thank you!
