On the whole the Hale Kukui Cottage (65-1252 Laelae Road) is a sweet suite. The small but complete kitchen was surprisingly well kitted out, with quality dishes, cutlery, pots and pans, sharp(!) knives, and nearly all the cooking utensils and small appliances you might want for a short stay. The full-sized fridge with ice maker in the pantry was a big bonus, as was the full-sized washer & dryer. The unit is spacious, bright, comfortable and tastefully decorated. You can see the top of Mauna Kea between the trees from the front porch, and Waimea/Kamuela offers a wide variety of interesting places to eat and shop for provisions. My wife loved the big soaker tub in the bathroom, and there was plenty of hot water. We were pleased to find beach towels, masks, snorkels and fins for two people (Hapuna Beach, a great swimming/snorkeling beach, is only a 20 min drive), and the two hand-finished wooden walking sticks were a classy touch that were a great help on our hike into the Pololu Valley. The unit has no built-in heating (that we could find), but the portable space heater was sufficient to take the chill off when it was cold outside. The WiFi worked seamlessly.
On the minus side, the family that lives upstairs has 1 or 2 young kids, and when they had friends over it got to be rather noisy. Most of the time, though, noise levels were no more than you would expect from people living above you. Also, although spotless, the place is a bit long in the tooth (several minor stains in the bedroom carpet, rather well-used couches in the living room), but we nonetheless enjoyed staying there.
