We were welcomed at the station by Stefano, Paolo's brother, who took us to the apartment and explained, in excellent English, how it worked and gave us helpful advice on local cafes, restaurants etc. The apartment was very well located and easy to walk to all the main attractions. There are lots of good places to eat nearby and the street is fascinating - a real mix of craftsmen, shops, and Florentines of all descriptions going about their daily lives. Slightly scruffy but very close to an exclusive shopping area. The apartment is delightful and well equipped. Also lots of useful books.
It is a bit noisy from street activity but if you close the windows and put on the air-con this ceases to be a problem. Just make sure you get instructions on how the air-con works. It all felt very professional and friendly.
