First of all Giuliano and Caterina could not have been better hosts.
This ancient flat was their home for many years and retains that homey feel.
We ate at some of their many suggested restaurants and they were all superb (Trattoria Cibrèo, Pizzaiuolo, and Ristorante Vivo).
Also the apartment was the cleanest Airbnb we have seen.
Nearby restaurants/bars were very convenient for breakfasts and snacks.
I should point out that, in a very hot week in July, mosquitos in Florence may be a problem.
