In a word - "Wow!" Mariacaterina's apartment was everything we could have hoped for: beautiful, clean, spacious, convenient and with a view that you will not surpass anywhere in Venice. If (when) we visit there again, we will build our trip around the availability of this apartment.
Even though we dined at a number of nice restaurants in the vicinity during our stay (they are plentiful), nothing surpassed sitting on our private balcony right on the water with a bottle of wine, cheese and fruit.
Mariacaterina was also an incredibly helpful and responsive host. She happily coordinated our water taxi back to the airport that picked us up at the apartment's private dock. The logistics couldn't have been any easier.
Hands down our best Airbnb experience ever!
