My hometown is a small city close to Florence, overshadowed by the capital of Renaissance but full nevertheless of little, outstanding architectures, sculptures and works of art that date back to the Middle Age.
Here is the town's history from Wikipedia:
Pistoia is worth a day trip from Florence, or a morning stop on your way to the more renowned (but not more important) Lucca and Pisa. Wrapped in the green embrace of the Apennines, it provides nice strolls for art and architecture lovers, as well as pleasant excursions on the mountains beside.
How to get there:
the closest airports are Florence and Pisa. Florence is directly connected to the main cities in Italy and Europe with companies as Alitalia, Lufthansa and Austrian.
From Florence, take the A11 highway leading to Pisa, Pistoia is just 28km far. Otherwise, trains and buses run regularly every hour from Florence main station.
Pistoia can provide a nice, cheaper accommodation for those who want to travel around Tuscany.
