Martin's place is really good, it is new, well-decorated, well-prepared. You don't need to worry anything about the comfort and facilities. Martin is warm hearted, he answered my questions in couple of hours, and set things up as I asked before the trip. The pool is beautiful, and bedrooms are amazing, without those we can not have the hard-core activities in Honolulu. Really subjectively, there is no bad side of my experience.
There are a few things may influence your choice, it still needs 20min drive to waikiki, the hot water is limited in volume, so if you use too much water, it gonna be cold.
