Fondamenta Misericordia is a little bit off the main tourist route and well worth the detour to get a more Venetian resident experience. There is a fairly unique supermarket (Despar - unique for the building interior rather than the goods) only 2-3 minutes' walk away so you can stock up and make use of the good kitchen facilities. There is a compact dishwasher and also washing machine if you want an extended stay. Staying for only one night was our biggest mistake, not least because the Airbnb and cleaning fees make it rather expensive. A week would've made the apartment much better value, but we had to get back to the US.
