From the airport to the city,

Anyone who wants to get into the inner city quickly and easily can either take the train from Fiumincino to Stazione Termini, or go by bus from the airport terminal which takes just 30 minutes to get to the city (also Termini). Both options are considerably cheaper than taking a taxi. For example, the bus costs just €6.
