Long-distance buses provide inexpensive if somewhat claustrophobic service between Florence and other cities in Italy and Europe. Lazzi Eurolines (Via Mercadante 2, Santa Maria Novella. 055/363041. www.lazzi.it) and SITA (Via Santa Caterina da Siena 17/r, Santa Maria Novella. 055/214721. www.sita-on-line.it) are the major lines; they have neatly divided up their routes, so there's little overlap.
