Before coming to Firenze, we stayed both at Milano and Venezia . Claudia's apartment was by far the best we have stayed at in Italy.
all the room's had air-conditioning and the apartment was very clean and neat.
we were a family of 9 person and had no problems at all to fit.
remember that the apartment is basically in the heart of Firenze. so if you come by car. your best chance is to park at garage nationalaze.
for 2 nights we paid 72 euros. it was expensive but the parking was very hassle free and less than 2 min walk away from the apartment.
I would absolutely recommend Claudia's apartment to others.
