After reading all of the reviews and visiting all I can do is copy and paste from a previous review that was spot on (Plus a Monk Seal visited the beach several times):
Wow, we had a wonderful week here. I'll divide my review into a few sections:
First: the physical location of the house is RIGHT. ON. THE. BEACH. (At least the time of year we stayed there). We relaxed, cooked, ate and slept to the sights and sounds of the gorgeous west Oahu coast. We could walk right out the back gate, onto the softest sand. The corner of the beach right by the house has the big waves, but we strolled down a few minutes to the calmer, middle section of Makaha beach and played in the much calmer waves there (a turtle swam right up to us!). It was easy to run back to the house to get snacks or supplies or sunscreen or whatever you forgot. At the far end of the beach was a great local surfing spot, and was also manned by a lifeguard.
The house itself: it's really well stocked in terms of beach stuff (umbrellas, chairs, boogie boards, toys, inflatables), bedding, towels, tableware, cooking supplies, cooking oil and spices. The two front rooms have A/C and the back rooms have ceiling fans. There is one floor fan that we used in the back bedroom to help with airflow. The back rooms would get quite warm & stuffy in the afternoon, but opening the front door to let the breeze flow through really helped. There's an outdoor shower to rinse the sand off your feet. The view of the ocean from the kitchen made cooking a joy instead of a chore. The front security gate felt good to have.
The local area: this is the one aspect of this listing I would caution folks on. If you want a resort-like neighborhood with manicured lawns, fellow tourists, high end grocery stores, trendy restaurants and cute shops, you will be disappointed. This house is in an area where locals live. Additionally there is a lot of visible poverty close to the house: homeless encampments on nearby beaches (though not the beach behind the house), cheap fast food restaurants, etc. The local grocery store we visited, Tamura Super Market, doesn't have the best produce or organic stuff/meatless options, but it did have a lot of variety.
However, there are some great hikes nearby and the ocean and mountain scenery are always breathtaking. If you're into stepping out of the house and eating at great restaurants and strolling in lively, bustling shops, this is not the place for you. But if staying at the house itself and enjoying everything it has to offer OR driving to other destinations on the island is your bag, you will have a fantastic time.
