If you're staying in Arezzo, it is a very historical town. There is plenty to see historically, but also there is the main square "Piazza Grande" where there are enough bars and restaurants for the evenings. The region is also a wine-making region so there are plenty of day-trips out to visit vineyards. Here are a couple of useful links to have a look at:
