Don't Miss the Metro
Fortunately for tourists, many of Rome's main attractions are concentrated in the centro storico (historic center) and can be covered on foot. But not to worry, wherever your feet won't take you, the Metro most probably will. Some sights nearer the border of this quarter can be reached via the Metro Line A, nicknamed the linea turistica (tourist line), and include: the Spanish Steps (Spagna stop), the Trevi Fountain (Barberini stop), St. Peter's Square (Ottaviano–San Pietro Musei Vaticani stop), and the Vatican Museums (Cipro stop), to name a few.
Tickets for the bus and Metro cost €1 at any tabacchi (tobacco shop) and at most newsstands (the price may go up to €1.50 by 2013). These tickets are good for 75 minutes on buses and trams, or a single Metro ride. Day passes can be purchased for €4, and weekly passes, which allow unlimited use of buses, trams, and the Metro, for €16.
