I come to the Venice Bienniale since 2001 for the Pre-view- I like Dorsoduro because I don't feel me in the touristical Chaos. It is calmer and also very near to many nice places. the museums and the Galleries. Also it is very easy and quick when you come from the both Airports (Marco Polo and Treviso) and also from the the Central Train Station.. The flat was very nicely and newly decorated with many facilities. Clean and orden. We didn't eat and cook there because of the Venice Bienniale Marathone, but there is every thing in the kitchen to use. So I can highly recommend you:)
