Florence is equipped with hotels for all budgets; for instance, you can find both budget and luxury hotels in the centro storico (historic center) and along the Arno. Florence has so many famous landmarks that it's not hard to find lodging with a panoramic view. The equivalent of the genteel pensioni of yesteryear can still be found, though they are now officially classified as hotels. Generally small and intimate, they often have a quaint appeal that usually doesn't preclude modern plumbing.
Florence's importance not only as a tourist city but also as a convention center and the site of the Pitti fashion collections guarantees a variety of accommodations. The high demand also means that, except in winter, reservations are a must.
If you find yourself in Florence with no reservations, go to Consorzio ITA (Stazione Centrale, Santa Maria Novella 055/282893). You must go there in person to make a booking.
