Actually there's not much else to say, flat's description and photos are true, all the infos from previous guests as well :) You will find there whatever you need for a comfortable stay. Indeed, it might be a bit noisy at night, but it's Italy, what would you expect? ;) I may add, that next to the nearby supermaket Conad, there's also pharmacy and if you go further that way, you'll find Piazza L. Ghiberti with a huge market place. Other things in Firenze you have to discover by yourself ;)
We haven't met Paolo, but his son who let us in appeared to be a really nice and helpfull guy (chianti was good, thanks!)
Well deserved five stars, highly recommended place!
