Terrible experience in Pisa
I had my first melt down on my solo trip here. The people are not friendly and there is nothing to do except the leaning tower of pisa. Pisa is not a place that needs much time to explore. It was really cheap to get to La Spenzia to do the hikes in Cinque Terre though.
Insider Tip:Do as quick stop if you are really dying to see the leaning tower.You will need a max of 20 min in this city.
