The house was centric, everything is walking distance, all very tidy and clean, 20 min walking from the bus/train station (8€ - 10€ by taxi).
Florjan received us and gave us all kind of direction and tips to do (He change our room to a bigger one, because the water wasn't working, so we end up in a more comfortable place).
For your advice, just make sure you leave right on the check out time, otherwise they're going to came in and start cleaning the apartment, even if you're not ready.
We enjoyed our stay in Florence, thank you very much!!
