I don’t recommend spending a whole lot of time here. Firenze (Florence) is an hour away by car or train and is a much more vibrant and interesting city. Pisa has the leaning tower and the church grounds it sits on…honestly not worth more than 5 hours of your time. Staying over night (it doesn’t have much of a night life to speak of) would be a waste of time better spent in Firenze. Just a humble opinion of this traveler.
