Siena

Roma Termini
Metro A/B meet under Termini; taxis use the official rank on Piazza dei Cinquecento.
Alternatives, honestly compared
Bus: FlixBus and Itabus connect Siena and Rome for less money but roughly double the time — the budget backstop. Driving: around 230 km on autostrade; add tolls, fuel and city ZTL zones (limited-traffic areas with cameras), which make cars a liability in historic centres. Flying only makes sense with checked bags and airport-side hotels — city-centre to city-centre, the train wins on this route.
