We rented the yellow casita, which means small house, and that is exactly what it is, not meant negatively; it is a small version of a real house with everything in it that you need for a nice vacation. The only thing missing in this casita is a kitchenette, but I understand that the other casitas have also a kitchenette. It was not a problem for us, because we stayed only a few days. There is a fridge so you still can make your breakfast if you want.
The location was great for us. It is next to the donkey sanctuary and we liked that very much. When we went outside we had always some donkeys in view and we fed them the breakfast leftovers and we bought some vegetables for them. No noises at night that woke us up as is suggested in another post.
It is in the middle of nowhere and that makes it a nice quiet place. And Aruba is small so distance is not really a problem if you have a car.
We will certainly book there again if we need a place to stay for another occasion.More
