Wow.. this was ideal for our stay in Venice, I can't recommend it highly enough.
The apartment is located just a couple of minutes walk from the sea front and the San Zaccaria water taxis to anywhere on the island or to the airport. And it's just a few minutes further walk to the amazing Doge's Palace and San Marco square.
The apartment itself was very clean, with two large bedrooms either side of the living area, along with a bathroom with a great shower and a decent sized kitchen. Just be careful on the steep steps up from the street (but there's only a few).
And the host was amazing, answering questions during our stay promptly and allowing us to check out several hours later than normal to accommodate our evening flight time.
Perfect apartment for the perfect city.
