First of all, BRING CASH. The hotel does not accept cards. I almost ruined my only day on the island searching for someone to give me cash because the only two ATMs weren't working.
Second, this is one of the most stunning locations I've ever stayed at. You really shouldn't miss it. The rooms are simple and clean but your door is like 10 feet from the turquoise ocean water with a view around part of the verdant, mountainous island. It's private, quiet, and there aren't other hotels on top of each other. There are hammocks. It's paradise.
Third, there is no hot water. Whether you need it there is debatable (it's not frigid either), but it would have been nice.
Fourth, the hosts, besides not accepting credit cards, were very gracious and helpful in helping us get our bearings around the island and getting anything we needed.
