For a family of 4, this space worked very well. I had specific needs and this space met all my requirements. Having two toilets helped ensure everyone could get ready in the morning (a full bath and a half bath).

Marco was very responsive. He was kind enough to allow us to store our luggage ahead of the check in time. He met us at the boat stop and walked us to the apartment.
Location was excellent, away from the crazy crowds at San Marco's Piazza, but still within walking distance. The main street outside the apartment has a grocery, and lots of restaurants. There is also a fresh fruit stand just outside. In particular, make sure you go to Nevodi, steps away from the apartment - it was the best meal we had in Venice.
We did not do any cooking, so I cannot comment on the kitchen facilities. It would have been nice to have an electric hot water kettle, but that was not a problem for us since we had coffee outside every morning.
