We had a lovely stay in Chiara's flat. I stayed there with some friends for a birthday and it was perfect. The little terrace is really nice, and the flat in general looks exactly as in the pictures. Located very close to the historical center, we could do everything in Rome by foot. The Trastevere neighboorhood is really cool with bars and restaurants.
The access to the flat from the Fiumicino Airport is easy (30 min train than tram or walk).
Chiara was always avalaible to answer our questions, and i would recommend her flat and book it again if i come back to Rome.
