Very nice experience with Donatella, she's very kind and had wait for us till midnight as we had been late due to traffic jam. The flat is small but full of remarkable hand-made furniture and just a few minute walk to every important church and monument in the middle of Florence.
If you choose to spend some time here you'll not regret it.
And try your breakfast at Dario's bar, a very tiny place near the flat, your day will start in the better way!
