This is a great place to stay. It's in a quiet neighborhood, but within easy walking distance of at least a dozen ethnic or high-end restaurants and other interesting businesses. By car it's 10 minutes to downtown or Waikiki at most hours. Excellent value for money; my compact rental car cost more per day.
As others have mentioned, it's modern and spacious. We appreciated the dedicated washer and dryer, reliable hot water and an A/C in each bedroom. The living room is furnished in Chinese style. Weon is a responsive host -- helpful and easy to talk to. When the coffee maker broke, he replaced it within minutes.
The only negatives:
1) Small cockroaches. Be prepared to clean surfaces thoroughly after meals and to plastic-bag your food, even inside the fridge. In all fairness, insects have been a problem in every house we've rented during 20+ stays in Hawaii, so it's not Weon's fault.
2) No local stations on the TV, which we solved by live-streaming the KHON news on a laptop or smartphone.
