We stayed at the casita for a week in March 2016, and it was exceedingly beautiful there. The grounds are gorgeously landscaped with an abundance of flowering plants, which is very special on a desert island. The outdoor spaces are the very best thing about this little home: there is a "beach" area near the steps that lead to the Caribbean, comfy covered seating areas, and lovely spots to sit and eat outside. There was a constant breeze and it was delightful to sit outside. Indoors was not quite as plush: the main seating areas are wood (with pillows) and the beds were quite firm. Sort of a church pew experience overall. The kitchen was small but perfectly adequate, and we really appreciated having basic spices and supplies (e.g., dish soap, sponge) available for us. The bathroom was very spacious, but (as Americans) we wished there had been a shower curtain to keep the floor outside the shower area dry. It was slippery when wet! Also, the indoor lighting was very dim throughout.
Our only disappointment with the property was that the dryer was broken, and we learned of it only through repeatedly trying to use it without success. There were clotheslines and pins available, but it takes a lot more time to hang clothes out to dry, and that's not how we hoped to spend our vacation.
The owner was very helpful. She answered our questions, provided excellent directions and guidance, and very promptly refunded our security deposit. There were lots of helpful items available at the casita, from coolers to beach towels, and even extra snorkeling gear.
Overall, it was a really lovely place to stay. As the sea washes up against the cliff, you can feel the impact of the water on the rocks as you lie in bed at night. It makes you feel like you're a part of the setting, and in beautiful Curacao, that is a wonderful thing.
Finally, if you are a snorkeler, the trip south to Tugboat and Director's Bay are very worthwhile: beautiful, diverse, healthy reefs. :-)
