What an amazing location!
Because the apartment is in the centre of a block, and not too high up, it is well shielded from noise, which is unusual for the centre of an Italian city.
And the terrace (and living room) has an amazing view of the Duomo.
And it is so central; a minute's walk from the Duomo, two to San Lorenzo, five from San Marco.
And a great little convenience store (which bakes its own bread) just across the traffic free street.
The wifi wasn't good, but there was good 4G reception in the apartment.
Marco gave us a free walking tour for over two hours.
The best AirBnB we've stayed in; couldn't recommend it more.
