We had a nice time at Elisabetta's appartement and it is definitely a good value. Communication was good, the place is big and you really have the feeling to be in an authentic neighboor of Venise. We loved the view from the kitchen!
The water boat is not far (Fondamente Nove not Ca d'Oro line 1), once you find your ways (not easy in Venice), you are 15 mns away from St Marco/Rialto, you have lovely trattorias and bakeries around. I just hoped that the welcome would have been "warmer" with a few things for the first breakfast or a bottle of water in the fridge, a heater already on (we stayed in the appart in Feb) and an extra pair of sheet. But as whole, a nice place to go for a week.
