If Elena's place is available for your dates, we'd suggest you look no further. It is a beautiful, light, comfortable and clean apartment right in the heart of a great location but quiet and with a lovely outside terrace. There is a vaporetto stop only a few steps away but we walked to most places. There is a good co op supermarket about 6 minutes walk away and a brilliant local's pizzeria, Arte della Pizza just hidden round the corner off the main street. You can easily get away from the busy streets and wander along the quieter streets and canals. We found lots of free exhibitions just wandering along and took in some of the best views of Venice from their windows. Elena was great, very communicative, and waited for us even when our plane was delayed and we got off at the wrong bus stop from Treviso airport- a tip - you are not in Venice till you have crossed the water!
