This was a charming fabulous apartment immediately on the grand canal across from the fish market -- a magical deck provides never ending entertainment of passing boats, tourists trying to stay upright on the traghetto, gondoliers preparing for their day, and the bells ringing in the near distance. The neighborhood (Cannaregio) is close enough to the stunningly crowded tourist areas if you care to pay a visit on foot, but also far enough away to really enjoy the city and some of its quieter neighborhoods. Cicchetti restaurants are close, the boats for Murano and Burano are a seven minute walk (ditto Alilaguna to/from airport). The market provides fresh food (but no odor in case you were worried) for any type of meal you can think of, but particularly seafood. Do make sure you do your homework on restaurants in Venice, as they vary wildly in quality.
The apartment itself consists of a medium-sized bedroom with ample storage for a longer stay that is away from the canal side and so pleasantly impervious to most sound; a small and clean bathroom; and a kitchen/living room with seating for a small dinner party. There is plenty of extra bedding as needed. The apartment is well-equipped (except perhaps a dearth of wine glasses) to eat any meals at home -- food processor, microwave, usual array of appliances, including a dishwasher. (Note, however, that there is no Wifi if that is important to you.)
The firm that runs this listing (Grimaldi) were immediately responsive to all communications and very pleasant to work with. When I requested an early arrival time because I was disembarking from a ship at 8am, they sent an email, complete with various links for breakfast spots, the appropriate vaporetto line, directions to their office, and an invitation to store our bags until the apartment was ready. In fact, when we arrived, they were incredibly friendly and were able to let us in immediately. (The apartment is about a hundred yards from their office.) The few questions we had during the stay were quickly and accurately answered. If there was one downside, it was the lack of an umbrella for shade on the sun-drenched deck.
I would not only return to this very apartment, but would plan to stay many more days than the three we did.
