My wife and I stayed at the Ho'okipa Hideaway for four nights during our recent trip to Maui, and overall we enjoyed the stay.
On the day we arrived, Claire greeted us. She was very pleasant and welcoming. She offered up some tips for places in the area for dining, which we took advantage of. (We went for coffee and/or breakfast at Baked on Maui every morning)
The Hideaway itself was charming. It was not very big, but size-wise it felt perfect for a couple on vacation. Everything was clean and organized thoughtfully.
We appreciated the beach gear that was provided, some of which we used. One thing that would've been nice to have is a place to hang and dry a sandy beach towel. We came back from the beach with a couple wet, sandy towels, which we ended up hanging over the outside door in an attempt to get them dry, but the outside humidity prevented that. There wasn't really enough space on the bathroom towel rods to hang them in addition to the bathroom towels we used for showering.
Location-wise, this place is great. It is tucked away in a quiet neighborhood, away from the hustle and bustle of tourists driving about on the main highway, but it's still just a short drive to get to some good dining or shopping options in Haiku or Paia.
Our main complaint with the place is the poor nights rest we got. That is partly due to the bed, which we both thought was too soft (we have a preference for a firmer bed), and I understand that could be just a matter of personal preference. But it was also due to the heat and humidity. I get that is just part of being in Hawaii, but I feel like there could be better solutions to mitigating it. In the rental there is a ceiling fan over the bed, but it is quite weak, even on its strongest setting. Also, there was a floor fan unit which did provide cool air, but it was way too loud for us to be able to sleep, so we didn't use it at night.
Overall, we both enjoyed our time at Claire and Billy's, and we would consider staying again the next time we find ourselves on Maui. If our sleep was better, this would easily have been a five star experience.
