This place is a great size for one or two couples, and centrally located on the island. ~15 mins from the airport, 45 from Hanapepe, and 1 hour from Waimea or Princeville. A/C was also very helpful for my wife and I's sleep.
Right across the street is a great bike trail, and with included biked on premise, a fun opportunity to take in the sites. Not to mention only a few minutes walking distance to swimmable beaches and downtown.
Speaking of Downtown Kapa'a. If you're able to, try and schedule your visit to be there during one of the "First Saturday" blockparty/market places. It's a great time, and we lucked out with our stay and the timing.
The host and onsite folks were accommodating and quick to respond, and helped us with any questions we had. They also provided a lot of local recommendations for things to do and places to eat/drink.
I would stay here again, given the opportunity.
