We need to get to Siena as early as possible on a Thursday in August from Florence. I have been told that we can leave our baggage (2 suitcases) at the bus station in Siena so thought the bus would be best. Then I was told a bus would take 2.5hours from Florence! Maybe we should consider the train (but we still need somewhere to leave our baggage until 3pm when we pick up our hire car from Siena Downtown). Help! And thanks!
