Great location! It's less than a 5 minute walk from the the Firenze SM train station and a a 15 minute walk to the Duomo. Many restaurants in walking distance so we really loved the location. It's one of the more spacious airbnb we've stayed at in Italy so it was a great value, especially if you're traveling with a group. Little patio area was also lovely if you want to have a glass of wine at night.
My only suggestion is it would be nice if the hosts kept spare umbrellas in the apartment. There was a rainstorm during one of the days but luckily it finished by the time we had to leave as we were told there werent any umbrellas. It would be helpful since most travellers don't really pack umbrellas.
