One of my favorite nights in Florence was spent sitting on the fountain at Piazza Santo Spirito. The whole vibe of this square felt incredible authentic and just far enough removed from the hustle and bustle of Florence..quaint restaurants, and tons of people just hanging out and enjoying the night. My suggestion is to buy your wine at one of the groceries around the corner from the Piazza (you will save yourself alot of money), head to Gusta Pizza, and place an order for 1 Gusta Pizza, then go sit and enjoy one of the best things you will ever put in your mouth by the fountain! If you can add in a few great friends, it will be a great night.. I promise.
