Francesca's flat is good value for money. It is situated away from the centre of Rome, but just a few minutes walk from the Metro, and absolutely surrounded by bus routes which took us anywhere we wanted. Francesca keeps the place tidy and clean, and her supply of cereals and cakes takes away the need to do shopping for breakfast.
To get there from Ciampino take the shuttle 720 to Laurentina and then either the Metro to Marconi or the 30 bus.
One slight frustration was that the local convenience stores keep short hours so we had to stock up during the day.
But we had a great time in Rome.
