The leaning Romanesque style tower has attracted people since it began tilting during construction. Here are a few quick things to keep in mind if you decide to see the tower:
The Leaning Tower of Pisa is a sight worth seeing, but I wouldn’t suggest staying in the city since you won’t need a full day to see it. Florence is close enough for you to get there by train [about an hour] and stay for an afternoon.
If you are coming just to see the tower from Florence, the best station to stop at is Pisa S. Rossore. It is much smaller than the central station but much closer walking distance to the tower.
If you want to go to the top of the tower, reserve your tickets in advance. This can be a real time saver during the peak season. You can purchase them here: http://boxoffice.opapisa.it/Torre/index.jsp.
