Florence is always buzzing with tourists, you will find them in large groups surrounding attractions such as the Duomo di Firenze, even in the worst weather. If you are looking to visit and experience warm weather, head to Florence in early April before it becomes too hot and humid in the city. The restaurants and cafes will open up their outdoor seating when the warm weather rolls in. If you're looking to escape the crowds, January and February deter some tourists due to the cold. Try to avoid traveling to Florence in August because of the smoldering heat. Many Italians flee the city to go on holiday and because of this, most popular shops are closed for the month.
Bus stops have clear, schematic labelling of the routes and are all named according to the street name or major landmark nearby. They do not always give an indication of bus times, however, so it is sometimes difficult to figure out how long it may take till the next bus arrives. Tickets must be bought in advance from Tobacconists or newspaper sellers, and are usually valid for one hour over the whole network, so that you can just hop on and off at will. They cost €1.20 for 90 minutes, and multiple day tickets are also available. Tickets are also available on the bus, sold by the driver, at an increased price of €2 (therefore, no more excuses in case of ticket control).
Better value is the €5 day ticket also from Tobacconists or news agents, best to add your name to the ticket and show your pass if needed by ticket control.
Tickets on first use need to be inserted into the ticket machine on the bus.
