Car rental - please provide a suggestion to rent a car on the north side of Rome to then travel to Siena. Where/who do you recommend I rent from? How long in hours/minutes to travel from Rome to Siena? Thank you
Here is Ron in Rome's page on cars. The first three articles are must reads: http://www.roninrome.com/transportation/driving-italy. For travel times, use http://www.viamichelin.com/; this will also estimate tolls and gas costs.
