It's a little hard to find, as most of the bungalows are occupied and some have similar addresses. My suggestion is to drive all the way down the tiny street, until it curves to the left and drops you on a flat boat dock area. It's one of the doors that faces out towards the water.
Also, there's a cafe that opens up, next to it. Pretty good food, but there is no convenient store or bodega nearby, so bring provisions.
John was nice enough to leave some cookies, which we ravaged over the evening. Yum!
