From Fiumicino (FCO), follow signs to the official white taxi stand. Ignore anyone inside the terminal offering a ride. The fare is fixed at €55 including luggage. Confirm this with the driver by asking "Tariffa fissa?" before departing.
Alternatively, take the FL1 Regional Train to Stazione Trastevere (€8) then Tram 8 to Arenula/Cairoli, which avoids the chaos of Termini. Note that the FL1 is not the more obvious Leonardo Express (which runs to Termini), and the airport train station is located over by Terminal 3.
We recommend Bus 40 (Express) from Corso Vittorio Emanuele II. It avoids the local stops of the 64 and provides a swift 20-minute transit to the main rail hub.
The closest taxi station is on the far side of Campo de' Fiori at Piazza di San Pantaleo. The next closest taxi stand is at Largo di Torre Argentina. Uber does exist in Rome but may take much longer than a cab; Uber may be cheaper than a cab, but that is not guaranteed.
Set up your account and install the app before riding, and start the ride directly through the app. Scooters and e-bikes can be fun and convenient, but they are expensive and dangerous. Avoid crowds and fast traffic, and be careful on cobblestones and hills.
You can buy paper bus tickets (€1.50) at all tabacchi stores (tobacco shops, signaled by a white 'T' against a black background) and at the hexagonal green tourist shop / newspaper stands found in most piazzas. You have to validate your paper ticket in the machine on the bus or pay by card (not all cards work with tap to pay). They check for validated tickets on the bus and will fine you.
Standard train tickets need to be validated by using the validation machine at the station before boarding the train. If you purchase an e-ticket that has a barcode, you do not need to validate it. If you sit in the wrong seat/car on the train, you will be fined.
Pay attention to your stop: trains coming from the north will stop at Tiburtina before Termini.
Take photos of the car from every angle (front, back, left, right, roof, and each of the four corners) before leaving the lot. Having timestamped close-up photos at pick-up is necessary to avoid return fines.
They do not appear to limit liquid container sizes in carry-on luggage and do not ask for identification on domestic flights within Italy.
Which Renaissance bridge connects Regola to Trastevere?
Answer: A - Ponte Sisto.
Commissioned by Pope Sixtus IV and completed for the Jubilee of 1475, Ponte Sisto was the first new bridge built across the Tiber since antiquity, linking Regola directly to the bohemian lanes of Trastevere.
