Kona is very humid so I was initially disappointed to learn that the coolest setting on the central air conditioner for this unit was for 74 degrees F (23 degrees C). But actually the system was very efficient at dehumidifying the entire unit, which made the 74 degrees quite comfortable. There were ceiling fans in every room which also helped greatly with cooling.
The secure Wi-Fi was fast enough to stream videos. The complex provides a coin-op laundry. The instruction booklets in the unit implied that laundry detergent was available, but I could not find any. The local convenience stores did not carry detergents for single loads. Fortunately, I found some in Volcano Village (nowhere near Kona).
The weather was rainy almost every day, so I did not make use of the available beach equipment. Overall, the unit was clean and well maintained, everything worked fine, and I could not have been more satisfied. I have no qualms recommending a stay here.
