From Rome Termini, what station and the name, in Florence should I arrive to be near most Tourist attractions? Thank you!
You need to take the train to Firenze Santa Maria Novellawhich is listed on the official Italian railway website (below, in its English version) as Firenze SMN.
SMN is the main station, right on the edge of the historical centre and less than 10 minutes' walk from the Duomo. :-)
