Erica's Airbnb was great and her husband (who was a main contact person) was super helpful and quick in communication. The bus stop is a few minutes away on foot, and you can even walk to Piazzale Michelangelo in 30 min. The huge supermarket (Coop) is 10 min walk, too. The place sleeps 4 people comfortably. We highly recommend it, and would be happy to stay again next time we visit Florence. :-)
