I stayed at Ca' Sansovino for a week in early September. I visited the Biennale and many exhibitions around the city, and had to work meanwhile.
The apartment provided me with the perfect solution. The position is fantastic, close to many venues in Venice, as well as to the Accademia stop of the ferry, where many lines stop so you can easily get everywhere.
The house is clean and new, the kitchen fully equipped with all the essentials to cook. Every room of the house is big, and the bathroom is clean as well.
The owners kindly provided full assistance on any issue, the house has been cleaned and the towels changed once during the week!
Also, despite the central position, the surroundings are totally quiet, so the place is incredibly silent.
So, for these as well as many other reasons, I would strongly recommend Ca' Sansovino for a business as well as holiday trip to Venice.
