Rome's smallest airport
Ciampino Airport is the smallest and closest of the 2 that Rome has. The transfer from the airport to Rome can be by bus, there are several companies just outside the terminal, turn left and you'll see the stops. The cotral company buses are white and you get a ticket on the bus (or at a booth in the arrivals terminal). The return price is around 7 euros and it leaves you in the Termini station. You catch the bus back at the same place as arrival.
