This was an excellent rental and I would absolutely rent Kelly's place again!
The house is spacious, well-kept, clean, and had all of the amenities you could hope for. The kitchen was adequately stocked with cooking materials for meals at the house and all of the bathrooms and bedrooms were clean, comfortable, and equipped with everything you need. One thing that really surprised me was how comfortable the beds were - a rarity anywhere but especially welcome after long days of hiking and swimming!
We also really loved the location. It's a 2 minute walk to the Hukilau Cafe (a cute little diner), a 5-minute walk to Hukilau beach (great local beach!), and a 5-minute drive to the grocery store. To get to an eccentric and delicious group of foodtrucks is about a 15 minute drive, and a ton of beautiful beaches (Sunset Beach) are within 25-35 minutes in either direction. Not only that, it's a 10 minute walk to the La'ie Falls Trailhead and between 30-60 minute drive to basically any other beach, trail, or park you could ever want to visit during your time on Oahu.
Before we arrived, Kelly was very patient and helpful. She answered our questions about things to do, best places to eat, and what to expect out of the weather in the winter. She was accommodating at every turn and was always very quick to respond to any questions or comments.
One thing I will note about anyone planning a trip to Oahu: the island is not set up to be particularly walkable, so you'll need to plan your activities around where you intend to spend your days. Kelly's house is located on the northern side of the island, which is quieter and more residential than the southern, touristy side. We preferred this, but if you're looking to spend most of your time around Waikiki, expect to spend an hour driving there (and back). With all of the great stuff on the north side of the island, though, why leave? ;)
