The space is as pictured and my impression they care for it as well as they can. It is a typical antique residence, enhanced by multiple antique touches. If you have mildew/mold sensitivities, I’d be irresponsible if I didn’t say to be careful staying in Venice (a wet city that floods a lot with stone buildings) in general; and this place is no exception; the scent is stronger in the entry and in the stairwell, but it is present in the apartment.
That said, that and the heavy energy in some spots of the space were the only things I didn’t adore about it.
Quick and gorgeous walk to the center. They left snacks & gave detailed advice about the AC/heat and assistance with where I was going in the city. There is also a very convenient water taxi station nearby - including the water bus to the airport, which is only €15, every 1/2hr, and goes very quickly. If you love Venice visually, you will adore this space.
