Nice apartment in a gated community. Located on a quiet island (nearly all apartments with one supermarket about a minute's walk away, which has wine on tap, bring your own bottle). Didn't find any bars or cafés on this island, but they're about 5 minutes walk away on the next one. Same distance in the other direction, towards the sea, on the next island, is the jetty for the "river" bus. If not , the walk into the centre takes about 15-20 minutes, although it's easy to get lost in Venice at first.
The only noise we heard was the occasional boat in the canal outside the bedroom window, or one night, someone torturing a violin (it sounded in pain). Sue Ellen was helpful in suggesting places to eat.
