I was wavering between 3 and 4 stars on this one. I ended up going with 4 because I do think the price was decent for being Maui and close proximity to the beach. If you plan to spend a lot of time at the Charley Young Beach, this is probably a 5 star place to stay! So keep that in mind. My friend and I had too many other activities (day trip snorkling, road to Hana, driving up to Whaler Village/Dragon Teeth trial) that we only visited the Charley Young Beach on our last night for the sunset (it seemed like a nice beach, with less wind than some others we visited).
Some things I wish I knew before booking this air b&b:
AC: Both ac units are on power timers (no way to remove the timers) with a max time of 4 hours on. The AC in the bedroom is very loud and not very efficient (or the cold air just gets pulled out of the window that doesn’t fully seal). The room gets quite warm without the ac, but it will likely wake you up when it shuts off after 4 hours. The house rules specify the best way to cool the apartment is to open the front door and the sliding back door and let the wind blow through. We did that but weren't comfortable leaving it open after going to bed, so that only worked some of the time.
Bed: The memory foam topper on the mattress is very squishy and felt weird to me, not to mention trapping the heat.
Bathroom: no controllable exhaust fan, and the water never got hot (maybe this is intentional to keep down on condensation). This may not be a concern to you if you get a sunburn, as you will not be able to unintentionally aggravate it with water that is too hot.
All that said, the price was reasonable, which is why we picked it in the first place. We had no issues with parking at the complex.
