Will will fly into Rome. I want to pick up a car there and drive to Assisi and Siena and then to Piombino. We want to drop the car at or near the port before we get on the ferry. Does anyone know if there is a car rental place at the port and what the name of the rental place is so I can make a reservation?
Closest drop off I could find was Pisa and then a 75 minute train ride to Piombino.

Others may be able to find something I could not.
