Florence is a perennial favorite, but 2015 is sure to bring even more visitors to the Italian city, since it was recently named the world's best city for travelers by Conde Nast Traveler.
It's a historic jewelbox that's full of incredible art, museums, shops, and restaurants. The Duomo, the city's main cathedral, is the most iconic tourist attraction here, but there are tons of other world-famous spots, like the Uffizi museum, the Accademia (home to Michelangelo's David), and the Ponte Vecchio.
