It would be hard to find a better-located apartment, or one with as spectacular a view in all Firenze - high above the Arno between Ponte Vecchio and Ponte Santa Trinita.
Very nice, clean accommodations and Guido is both earnest and most accommodating.
The apartment is literally steps from all the musts (Duomo, the Baptistry, Uffizzi, Ponte Vecchio, Central Market, Pritti Palace, Boboli, Santa Croce). Many great trattoria and ristorante within a short walk if you do your homework. And you should as mediocre food abounds as well. We were there six nights and had fabulous food - fairly priced - every evening.
One note...if you are not in good physical shape, this apartment may present a challenge. It is four steep flights up and there is no lift. So...get in shape, this apartment is worth it.
