Andreas place is perfect to explore Venice, it's easily accessible with the directions he provides.
Be careful about the 8 o clock curfew he is very serious about it. We barely made because our travel plan was suddenly changed, and he told us that if we were late we will have to pay 50 euros fine.
In all fairness it was written on his website and we can't really complaint because he seems like a meticulous type of person.
Rest it was a great stay. Room was clean and with all the amenities.
