Location, Great Breakfast, Location
I can't decide which feature of the Hotel Calzaiuoli is better--the location or the breakfasts. It is centrally located, only a few blocks away from the Uffizzi, the Duomo, the Piazza Republica, and the Piazza della Signoria.
The breakfasts are great--especially the hot chocolate and the cappuccino--and not to be missed. The room is well-decorated, not fussy. The same goes for the service.
Though my boyfriend and I did not find the noise level to be unbearable, some might disagree, especially during summer nights, if the windows are kept open. Those persons who are sensitive to street noise should request a room that is not on the street side of the hotel.
I will definitely stay there the next time I visit Florence!
