We spent our honeymoon in this superb hotel and we got a wonderful room, the attic room, just beautiful. A nice walk takes you from the hotel to the San Marco Square and the Rialto Bridge, ect. There is lots to see within walking distance. Good breakfast, friendly staff that is willing to help you wherever possible. Three days is enough. Venice is not the type of city you go to for an extensive holiday, but three of four days is recommended, especially in this hotel.
