Go to one of the museums.
And walk around the city center.
Stay: Eden’s hotel, not expensive, near the city center.
Cathedral of Santa Maria del Fiore is without a doubt the most recognizable attraction in Florence. Also known as the Duomo, this 14th-century Gothic cathedral occupies the Piazza del Duomo. Admire the beauty of the pink and white marble exterior and climb nearly 500 steps (no lift!) to the dome for magnificent views of Florence.
