Giancarlo is a great host - very helpful and friendly. He met us at the train station nearby on arrival, showed us around the flat and even provided a list of great local and city restaurants!
The apartment is neat and clean. It is on a basement floor with windows and roller shutters. We felt secure there. The kitchen/living area is small, but was enough for a family of four to move about and eat together. The bedrooms are medium to large in size. The apartment is air conditioned, which in the heat of Summer was a blesding!
The apartment is a great base from which to explore the Vatican City (5mins walk) and the rest of Rome either on foot or by bus (the #64 bus takes you into the city and close to the Colosseum).
We highly recommend Giancarlo's apartment for a touring visit to Rome.
