We were met by Christina who gave us very good directions and was very hospitable and eager to help in any way. The apartment is very modern, comfortable, secure and spotlessly clean. It is located very close to Roma St Pietro railway station, so getting to and from the airport is easy (one change of train). It is also very close to the Vatican (make sure you pre-book your ticket to avoid a queue, and when leaving the Sisterne Chapel follow the route for groups only to take you into the Basilica directly.) There are plenty of local buses to take you into the centre of Rome to see all the main sites. Thank you Claudia and Christina for being excellent hosts.
