Great place to stay and visit every significant thing in Firenze, just by walking. No need for public transportation at all, except on the arrival.
The apartment had everything we needed, the beds are comfortable, and we enjoyed our stay there. We would most certain choose it again.
The host gave us some very useful information, so we parked the car near the highway for low cost prices (Villa Constanza parking), and came to the apartment by public transportation (T1 + C3 lines).
There are few very good places to eat around, we have enjoyed our meals in the Osteria across the street, with a good domestic chianti vine. Also, there is a bakery 30m down the street, making wonderful cakes.
