we had a great time at our stay on caye caulker in the purple pearl. the cottage was clean and comfortable, air conditioning and fans worked well at nighttime to cool us down. the cottage is set quite away from the main action on front street so we rented a golf cart to get around for the week and, with three small kids, were glad that we did. the cottage does offer bike rentals at a very reasonable cost but that was not an option for us.
the pool is fun and the deck has great lounge chairs--2 per cottage plus some regular chairs. very comfortable.
the kitchen was missing a couple items (namely, high-quality cookware for cooking fresh fish if you buy it in town, kitchen towels, and a set of decent knives), however the house comes with a very friendly manager named michael who can easily be reached by the provided telephone, and if you need something he can get it for you. we did not ask to get new cookware, but i'm fairly certain he could have done it. he did get us a couple of cases of belikin beers at the local's price which was great.
the water pressure in the purple pearl is not very great--but we had a different experience there than my parents who were renting the green cottage across from us. it wasn't a big deal but if a high powered shower is what you're looking for, this is not the place ;)
the house provided drinking water, a safe, a pre-paid cell phone and beach towels, all of which proved quite useful. we had a great time during our stay and were sad to leave the island and our sweet little cottage!
