I've been in Florence for ten days and I really enjoyed my stay at Fabio's place. I didn't meet him because he was out of the city but I was accepted by Fabio's friend, Paolo, who is such a great and kind guy. The apartment is generally beautiful and cosy. You have everything you need and more. There's a supermarket just out of the building, which is very convenient. You spend 25 minutes walking to city centre, otherwise you can take bus which is faster.
I recommend Fabio's place because he's been very kind and has fastly responded to my questions even though he wasn't in Florence. Wish to see you soon guys, thanks for all!
