Does the train station in Pisa, Italy have lockers for people to store luggage?
Pisa is not located on the train itinerary from Rome to Florence. If your hotel is in Florence you may leave there yr luggage and then hop on a different train from Florence to visit Pisa. It’s an hour trip to go there but you’ll need taking a different train since those ones arriving to Florence are not passing by Pisa. ADDED I see from yr additional details you go as first to Pisa and then to Florence. In this case at Pisa Centrale (Main Station) they’ve lockers to self-store your bags but sometimes they are sold out or out of service. In any case a left luggage office attended by an employee (3 Euro/luggage to 12 hours) is regularly working during the whole day . Have a nice trip to Italy.
