Francesco is a great guy and very helpful/responsive. He checked us in around midnight, on his BIRTHDAY, after we had complications with our flight that made us arrive very late. He was easy to talk to and quick to reply and help us out, including dropping off a replacement corkscrew when the one in the apartment broke.
The apartment is very nice and spacious with good natural light and private terrace to hang out on. It is a very central location with quick access to everything in Florence, while at the same time providing ample peace and quiet. I would recommend this to anyone and I would stay here again.
