The flat is wonderful: bright, airy, clean, stylish and with fantastic hosts. There are small touches like toiletries and breakfast that are provided including tea and coffee. We went for Nespresso.
The flat is in a perfect location if you are planning to attend a papal audience. It is also a good starting point for exploring the city. It is in a quiet location, right opposite one of the vatican gates, and with police and the army permanently stationed in the road outside, it is a very safe neighbourhood.
Andrea and Stefania are lovely hosts, and Massimo, the driver who can take you to/from the airport, is also lovely.
