We had an excellent stay at Pali Ke Kua #116. The views are outstanding with beautiful ocean views. Being on the ground floor, yes, you can occasionally hear footsteps from above, but nothing more than a typical hotel room. The 2 groups we had above us during our stay were quiet during normal quiet hours, so no complaints from us on that. It was convenient to hose yourself off on the grass after going to the beach and the daily morning visits from the Nene's was an added bonus! Not sure I would trade that for the occasional footsteps above. The unit is nicely updated and the AC unit in the bedroom was greatly appreciated!
The kitchen was fully stocked with all the typical cooking tools. However, there wasn't any basic spices (salt and pepper??) for use, so plan on purchasing items you will need to cook a meal (minus pots, pans, and tools). There is no BBQ grill at the unit, however one is available on the Hidden Beach walking path, but honestly, it would be a pain a carry stuff up and down that steep path. We didn't both with it.
There are a few sets of snorkeling gear, as well as coolers, a beach chair, umbrella, boogie board and a few other pool toys. No beach towels, so bring your own.
Overall, we highly recommend this unit!
