Stayed only 2 nights on a quick trip to Venice, will be back. Was fantastic.
Had a quadruple room which had a large sofa bed for our 8 year old son.
The owner and his son ( I assume) were very very helpful and attentive.
Warning. Get good directions from the owner to get to the hotel: involves taking boat 52 I think on northern shore. We didn't and were poorly prepared, and ended up walking for hours late at night in the deserted streets trying to locate it.
