Antonio's place was wonderful for our stay in Firenze! Right in the middle of the city, the Duomo is just two blocks or so down the street.
Firenze is a small city as is, so really everything you could possibly want is walking distance.
Antonio greeted us upon arrival and was very helpful with checking us in and checking out a map with us.
The apartment is shared with another room that's also a BnB and a few nights there was nobody else staying so we got the whole place to ourselves! On top of all this, the bed is gigantic and very comfortable.
Definitely a great stay, I highly recommend it.
