Getting around Rome by GK2005
Rome is well served by public transportation that eliminates the need to rent a vehicle or take an expensive taxi to go from one place to another. There are two metro lines, Line A (Red Line) and Line B (Blue Line) that serves almost all of the attractions in Rome. The combination of the Metros and the Cotral buses are enough to see every single attraction in the city of Rome.
