I made an account just to recommend a house my friends and I rented in Sally Peachy on Big Corn. The house belongs to Marlon Gomez and is located behind the Sally Peachy store and across the street from a volleyball court. It is not listed on trip advisor and I found it incredibly difficult to create a listing.
We found the house when we were walking around trying to find a place to stay and were able to negotiate. The house has two bedrooms with AC, one clean bathroom, cable tv, a nice fully equipped kitchen with an oven, a grill, and a laundry machine. Marlon and his family were very helpful and friendly. They offered us avocados, bananas, and bread fruit from their property as well as water from their well. This area of Big Corn is residential and a short walk to the beach in front of Yellow Tail House. We bought eggs, dry goods, and drinks from Marlon's store. We asked around and found lobster, chicken, beans, vegetables, bread within a short walking distance.
I found this listing for Marlon's house: http://www.bigcornisland.com/rentals.html
I highly recommend staying in Marlon's house and in Sally Peachy.
