I stayed at Enrico's place in Florence for a conference. It was incredible to stay at literally ten meters from Piazza della Signoria, with an astonishing view and a gorgeous neighbourhood.
The house is in an ancient building, with every comfort necessary.
As described in other reviews, the bathroom is small being the structure of the building from another historical time, but this did not avoid to appreciate the uniqueness of the house !
I would definitely come back to his place.
