My husband wrote a review on this unit, so I'll just add a few details that I wish I would have known, which may help you decide what to pack or plan to buy there.
I will say that the view from the bed, of the sunrise coming up over the ocean, was my favorite part of this wonderful trip. I went to bed early every night and awoke naturally around 6 AM to this glorious sight. Overall, great condo, and I would definitely recommend it.
2 beach towels, almost unlimited white bath towels
2 beach mats
4 or 5 boogie boards of various sizes
5 sets of flippers, of various sizes to fit adults or older kids, good quality
2 snorkels but no masks (the local shops rent snorkel and mask as a set, and The Hanalei Surf Company and probably others rent masks equipped with optical lens based on your glasses prescription, very worth the cost to rent for a week)
I think there was a beach chair and beach umbrella
2 sizes of coolers - helpful for grocery shopping, not just picnics
camping tent, etc which we didn't use or examine enough to tell you what was there
-Decent supplies overall except the knives were pretty terrible, smallish and dull. If you are planning to cook for the week, it might be worthwhile to buy an inexpensive knife set and leave it there.
-No spices, condiments, oil, etc provided except salt and a pepper grinder. It appears that the kitchen is thoroughly cleaned out between guests so don't expect anything to be left behind for you to use. In retrospect it would have been helpful to plan meals ahead of time and bring little ziploc bags with spices. I would suggest fish tacos if you are looking for ideas.
-Adequate paper products, dish soap for hand washing and machine-washing, etc were provided except there was only enough laundry soap for one wash. Some random stuff like white vinegar, rubbing alcohol, hydrogen peroxide, etc is onhand from what folks have left behind. (Vinegar is supposed to be good for sunburns.) There's a stash of sunscreens, aloe, and bug spray that others have left behind, enough to get you by for a day or two til you get your own.
-There is NO GRILL. The listing for the place implies that there is a central BBQ area for the complex.... there is, but it is as rustic as you can get. It's just a brick fixture where you could build a fire, etc, so you would need charcoal and the whole deal. There is a picnic table there so you could make use of it, but it's not what I would ever call a grill, and unfortunately we planned our meals around grilling and that was a bust.
-Everyone warns how expensive food is in Hawaii. Some things are outrageous, but lots of stuff is comparable to what we are used to paying at a natural foods store. Many reviews suggest using Costco, but if you are a couple staying for a week, that kind of quantity is too large. A good alternative is Cost-U-Less in Kapaa, right off the main road (on the non-ocean side of the road). Prices comparable to Costco, but smaller quantities, their produce is better quality overall, and I was pleased that they offered organic butter, cheese, etc for fair prices, as well as milk from local island-raised cows (not organic, but its local so not factory-farmed and so that's better than organic to me). The Foodland in Princeville seemed decent to us, and if we go again we'd probably get a lot of stuff there.
The nearby beach:
The hike down is slippery in spots, and Kauai mud in general is very slippery, so pack shoes with tread for getting down to the various beaches. Any beach that has a short (or not short) shady hike is likely to have mosquitoes, so consider wearing long sleeves and long pants for your hike-in (since it's not good for the water to apply bug spray before swimming). I got about a dozen bites on my way to this beach, and overall the beach itself wasn't worth it. I'm a novice snorkeler and didn't know til later that to get to the good stuff, you have to find the canal and swim out. I was trying to snorkel in the shallows and it didn't work. The coolest thing about this beach is the very course textured sand and some nice small shells.
You will definitely want a car for this location - I wanted to do it without a car, but glad I didn't. It's a decent drive from the main road back behind a golf course, which would be like a 20+ minute walk just to get to the road, and there are no restaurants or anything within an easy walk. With this location, you get the ocean view without paying for a beachfront unit. I wanted to visit different beaches each day, so that worked for me.
Security: Hide any valuables cleverly when you go out, and don't leave them sitting in full view at night. We saw a way that these units could easily be broken into (like most beach homes, frankly) so we were cautious. No problems though. We still felt safer leaving them at the condo than locked in the car.
The cleaning crew was responsive and courteous when we locked ourselves out. It's a husband-and-wife team. When we left, I asked if we could leave food in good condition behind, and they assured us that they would put it to good use. So that's good.
Overall, a very positive experience!
Have a great trip!
