The house is basically clean and functional. A really nice view, but in the middle of a residential area so be prepared to drive for anything you need, which is OK if you're prepared.
Be warned that there is no air conditioning, which is fine though I think this should be highlighted more explicitly in the review. It was often 90+ during the day in late July. Evenings were OK-ish by opening everything up and running fans. I think this is normal for Hawaiian houses, but if you're comparing against a hotel/resort just be aware.
Also, there were no beach towels, etc so be preapred to bring or buy your own.
