Andrea's apartment was perfect for our group (four adults (two couples) and one child). Spacious, clean, very centrally located but also sufficiently quiet at night due to the double glazing and shutters on the windows.
The supply of soap etc for the bathroom, detergent for the washing machine, coffee capsules for the Nespresso machine, and local restaurant/cafe/bar recommendations made things very easy as well.
Andrea was a wonderful host, helping us out with a number of questions that we had during our stay, booking us an early morning taxi, and being flexible on check out time.
The only slight issue we had was taxi drivers not knowing / being able to find the address. I suggest you just ask to be dropped off / picked up at the back of the Pantheon near the taxi rank - that worked for us.
Overall highly recommended. If we went back to Rome again, we would certainly look to stay at Andrea's apartment.
