I stayed for one week during the Biennale - a great place in the more touristy part of the City, but still quiet enough for a very good night's sleep. Central and walkable to all destinations within the city (5' to Piazza San Marco; 25' to the train station, 25' to the Biennale etc..) Be aware of mosquitos in Venice due to the canals, so if you don't like them, bring some spray. Also, the Internet in the apartment was slow, so if you also need to work, bring some patience (and maybe one shouldn't work in Venice anyway). All in all very recommendable!
