In a nutshell, I was a bit let down by Pisa. Walking round, there is a general feel that some of the vibrancy and life that the rest of Italy has to offer is washed away here. The tower isn't as spectacular as other towers in Tuscany, say for example Giotto's Campanile in Florence. It just happens to be on a lean. Others may disagree and feel more suited to the touristy vibe. I was mostly travelling there to use the airport.
Insider Tip:I did have a brilliant meal in Pisa though! A set meal with bread, salad, pizza, beer and great service for under 10 euros. It was on the main street leading up to the tower, towards the back though away from the crowds.
