Really enjoyed our stay here...
Location: good location if you like walking. 3 min walk to a supermarket. 15 min walk from the train station. 20 min walk to most attractions in Florence (except for Piazzo Michelangelo which is about a 40 min walk (well worth it for sunset though)). Can get tiring in the heat, especially if you have kids I imagine. Good way to save money though.
Apartment: bedroom was really nice with very comfy bed. Could do with supplying an extra pillow or two. Shower was powerful. All kitchen facilities worked well, not masses of room but the pictures reflect the size well. WiFi was good in every room.
Host: Matteo (someone who works for the hosts) came to meet us and was the most helpful of all of our hosts in Italy (all also with consistent 5 star reviews). Explained great spots for food and drinks, what sites to see, etc. Used the map so that we would remember what he was talking about. Very good at answering questions.
