My husband, who is a windsurfer, and I stayed at Casita 2 at the end of March and we were very pleased with the property. It is on Lac Bay, a 3 minute drive away from the windsurfing area, so it is very easy to go back and forth - either to eat, change, or pick up the things you forgot. You can also walk to the windsurfing area in 15-20 minutes if you choose. The part of the bay it sits on is not very swimmable, but it provides a lovely view and a great breeze.There is a nice area to sit out in front of the Casita, and a hose for washing your diving/snorkeling equipment.
Inside, the living area is utilitarian -not much furniture, but just what you need. The kitchenette has a refrigerator, stove, and a clothes washer as well as small appliances including a toaster and a blender. (Tip1: don't tip the blender upside down without the cover on to pour it out or the Ninja blades will fall out and get you! Tip 2: use google translate to decipher the Dutch controls on the washer.)
The bedroom had a very comfortable kingsize bed, and plenty of storage in a bureau and closet. There is a large screened patio with a picnic table out through the bedroom in the back. The bedroom is air conditioned and there are ceiling fans in the apartment as well.
What was really great about the apartment was all the extras the owners generously provided including big fluffy beach towels, extra sheets, grocery bags, an inflatable paddleboard, and bicycles (but you will need to be tall to ride them.) There was also reliable internet access and cable television and a music system.
The Casitas are a 10 minute drive from Kralendijk, and in a remote area, so you can't go walking outside at night. But you can sit outside and enjoy the stars, the breeze, and the "wild" donkeys that come to visit.
As another added bonus, there is a good restaurant next door as well. We would stay there again if we ever get the chance, and we recommend it to everyone who wants to be near Lac Bay (which, by the way, also has some of the best snorkeling on the island.) Thanks for the great stay!
