Recommended transportation from the airport to the city

In Rome, the train from the airport is a "recommended" way to get downtown, however, you may find that for two persons, a taxi is a preferable way to go.  When you consider the train fares, schedule, taxi fare from Termini station, and the train hassles, you may want to consider hailing a cab.  Cabs are less stressful after a long transoceanic flight; they are reasonable and comfortable.

Tickets on the Leonardo Express train are about 14 Euro per person, less on the Metropolitan FR1 service - although with that you'll have to change to reach Termini. 

Rome Termini Car Rental:

There are numerous car hire companies based at the two main Rome airports. Here is a link to a list at Fiumicino and at Ciampino.

What about taking a taxi?

You can pre-book a pick up in Rome if you do not want the hassle of haggling with local taxi drivers or if you are a larger group travelling together  http://www.romecabs.com/ www.romeairporttransfers.co.uk 

A cab between the city centre (within Aurelian walls) and FCO costs €48 Euro, or €30 for Ciampino; this is a set fare day or night - don't let them charge you more (they will try). Perhaps rather late now but, for a map of the area covered by the set airport fares, see...

Once you arrive in town, you can decide how to get to the attractions.  You should find Rome easy to walk EVERYWHERE.  You get to see more, meander in and out of shops, and it is no more than 45-50 minutes to any attraction you will want to see in major downtown areas.  You do need good shoes as the brick or cobblestone streets are tough on your feet and legs.
