Elena's place is great... Rialto and San Marco are so walkable.... Practically on the next block ( like 5 mins walk) is where you can catch the the No. 2 water bus that will take you to the train station ...There are also great restaurants/cafe/shops around ...and Elena is really nice and friendly... I will stay here again when I get the chance to visit Venice again. Also, if you're coming from airport, you can just take the waterbus and stop at S. Angelo ( from there, it's less than 10 mins walk to Elena's place ... So accessible and convenient ..
