We stayed in the doge palace 2. From our experience the location and the house were amazing just as the possibility for the luggage storage at the day of leaving.
Although we do have one minor point. The couch/bed/foldingbed in the living room was bad. We placed the matras on the floor in order to sleep comfortably. We recommended the owner to update this bed and truely hope they fix this. If so the place is amazing! If not we recommend to stay here with 5 ppl.
Even though these minus points, we had a nice stay in this beautiful city.
