We have stayed in a lot of cottages in the Caribbean; this is the best equipped one yet. We will sometimes buy an inexpensive kitchen item and leave it - cheese grater, garlic press, or something like that. I could not come up with a single item that we couldn't find on site. The bathroom includes insect repellents, sun screens, even contact lens solution - just in case you forgot something. The kitchen had everything we could imagine needing. And, of course, the washer/dryer (as well as clothes line) help reduce the amount of clothes to pack. The cottage is very clean and neat. And Sue even pressed us for any suggestions for how to improve it. But she is not an intrusive manager. She made it clear that the cottage and the beach were ours and that she would be out of the way. She was true to her word, but available on site if needed. She is also a very congenial host. With a little encouragement, we did get her to visit with us a bit and enjoyed her company as well as her experience on the island.
The property, including beachfront, is well maintained. Adjacent properties have rocks down to the water and the flotsam that shows up. Not so at Cayman Cottage. Sue removed the rocks long ago leaving a sandy beach and she keeps the debris picked up. Chairs and lounges on the beach have small tables for coffee cup, beer, rum glass, book, camera, etc. And she will remind you not to sit (or park) directly under the coconuts. The trees make good shade, but you don't want a coconut falling on you. Beach is beautiful. Swimming and snorkeling are good, but bring water shoes; all the islands have sea urchins that you'd rather not step on.
There are dive shops and restaurants less than a mile away, at least one restaurant in walking distance. We used the kitchen on the property, so can't say anything about restaurants. Liquor store in walking distance - we took the owner's advice to bring our own rum at about 1/2 the cost of the island supply. Grocery store about 2 miles away (near the airport). There is a bigger and better supplied grocery (Kirkconnell) on the north side in Stake Bay. Ask when fresh produce comes in.
I'm not sure if renting a car is essential. It's a long walk with groceries. Perhaps you could catch a ride? There is at least one restaurant within walking distance. The beach, the birds, and the fish are all on site. For birders the west Westerly Pond across the road is a great place for wading birds.
