This is the BEST location in Venice in my opinion. The neighborhood is near the historic jewish ghetto, away from the throngs of tourists and surrounded by the best little restaurants.

Don't be put off by the creepy entrance and moldy hallway, the apartment is very clean, modern and nice. Perfect for up to 4 people (the rooms are all pretty small so you wouldn't want more people in there). My wife, my sister and my 7 year old loved staying there.
