We will be arriving at the Ciampino Airport July 3rd at 10:40am. We need to meet friends that we will be staying with at the Trastevere Train Station. What is the best way to get there? I did a search and found that there is a Terravision bus that goes to the Termini station, can I then take a train to the Trastevere station? Do you know of any websites that may help me?
