The apartment is exactly as described: at the rim of the old town but only 10 minutes walking distances from the train station Firenze S.M.N.. It is spacious, clean and has a distinctive rural chic. The market is only 50m away and a great place to have breakfast or buy food.
Only take back may be the nightly noise (loud music) from the ground floor restaurants, which requires sleeping with the windows closed. There is no significant car traffic on the square, though.
The hosts are good to communicate with.
