If you want to have a romantic stay in Firenze in a authentic area, that's the place to be ! The flat is located near piazza Sant'Ambroggio, close to the center (10/15 min to ponte vecchio and 20 min to the train station, where from the shuttle airport leaves) and full of enoteca, restaurants and bars.
But still, it is quite and we really felt at home. But if you are very sensitive to noise (which is our case), you can hear cars in the street but there are not so many of them.
The appartement is fantastic : very well decorated and with everything you need. It's very charming and cosy. As it was cold, we could not enjoy the terrasse but it seems perfect to enjoy a drink after a long day walk !
Karen and Raffaele (who speaks a little bit french) are really kind hosts, they provide us good advices and tips (with their personnalized map which was very useful!!!).
We really loved our stay and definitely recommanded it ! Do not hesitate, you will certainly love it as we did.
