The door to go in is the one without a street number, a few feet east of the one numbered 1610 and well west of the one numbered 1608, pretty much in the middle of the block and across from rue Pierce (which is unlabeled at that intersection! - check the map first). You go in and down a few steps to a "Saint Cinnamon", past it, down a flight of steps and then around a barrier and down another flight. This might seem complicated, but we will put up signs to help you.
