We were a group of 6 people and took the entire appartment for ourselves. All the rooms are clean and nice. There is one common area where you can sit and have diner together.
A friend of Flavio, who lives across the street, waited for us at the appartment, to show us the place and give us the keys.

They respond to your requests within a few hours, are very helpful, and I can truly recommend this place. It's 8 min walking to the Vatican City. Wifi works good
