Tommaso's place was perfect. My sister and I organized a trip with our parents and her husband, for a total of 5. This worked out perfectly, with two queens and one sofa-like bed (very comfortable).
The location is just a few blocks from St. Peter's, so if your trip is Vatican-focused, it doesn't get any easier!
Tommaso was very welcoming, meeting us at the apartment to help check us in and give us a tour. He also provided fruits and yogurts for breakfast, which saved us a trip to the store.
Would definitely recommend!
