Traveled to Firenze with my family of 7. This AirBnB fit us all comfortably, had an elevator, AC in every bedroom (not living room), and was in a good location. Note you need to taxi to and from the train station. Otherwise everything else is a reasonable walking distance. Elly was extremely helpful and responded to any questions immediately. She helped schedule taxis for our early departure.
Although the garbage cans were noted on a map, I wasn’t able to locate them. I recommend asking whoever checks you in to show you where on the street they are.
Otherwise I’d recommend this AirBnb & come back again. The gelato at Gelateria della Passera right outside is SO good, definitely worth a try!
