This was the second AirBnB we stayed at in Firenze and it was much much bigger than the first. It is a modern recently refurbished large 1 bedroom apartment. It was very quiet, well laid out and easy to use. Roberta was very kind and let us check in early. The location is a little far out if you are going to the tourist areas everyday (15 mins to Duomo) but for Santo Spirito area it's fantastic. There are lots of really interesting, not tourist restaurants and bars footsteps from the apartment.
Roberta was really easy to deal with and had book prepared with restaurant recommendations and guides.
