We stayed at the Duodo Palace hotel for just two nights and everything was absolutely perfect. The staff were helpful in assisting with water taxis and suggestions for places to go and things to do. While the 3rd floor location was a bit challenging after walking countless miles in Venice, the room was spacious, comfortable and quiet. We thoroughly enjoyed the more than ample breakfast. The location is so close to St. Marks square and is convenient, yet quiet. We will definitely return.
