Hello! It'll be my first time in Italy. I'm planning to take the 365A Ferruzzi bus from Florence to Greve to stay overnight and visit some wineries. Does the 365A bus allow luggage on the bus?
Yes, you can most definitely carry luggage with you on the bus! You will have to handle it all by yourself on getting it on and off, without help from the driver, though, so make sure you can manage on your own.
