What is the best way to get from Siena to Florence? We have 2 options--we could take public transport or take our rental car. Our hotel is on the Via Fiorentina in Siena.Any ideas? We are going in May.
The SITA bus runs from Siena to Florence - they have a website. The last bus leaves Florence around 8:30 pm so that does not give you time to stay for dinner. I've driven in Florence - it is not that bad once you get used to being absolutely surrounded by vespas. There is a convenient parking garage by the Santa Maria Novella train station.
I took the Sita express bus r/t Florence to Siena last Sept. Bus ride was easy, mostly on freeway, A1 I believe. If you are taking luggage with you, know that stowage space is very limited beneath the bus, and inside, only room overhead the seat for small carryons - tote, small backpack. Because of this, when the bus arrived, there was a mad scramble to stow luggage. Some people had to wait for next bus because of this. Also, remember to validate your ticket. I did so on the bus but there are machines at the depot too.
