First of all, the location of this unit is great! It is a short (10-min) drive into downtown Kona for restaurants. We also found some great ones just south of the unit (the other direction from Kona). The balcony is wonderful, with a ceiling fan, comfy chairs, and front row seats to the surfing. We really enjoyed sitting out there. Also, the location was very quiet at night, and we never had an issue with parking in the garage or out front (both very convenient).
The unit is well stocked. The washer and dryer were very nice. Plus, laundry supplies were provided. We didn't cook in the kitchen, but it appeared to be well stocked. Plenty of extra towels (including beach towels) were provided as well as beach supplies (chairs, umbrella, boogie boards, etc.). There are two bathrooms with nice showers and plenty of counter space.
My only negative was that there is only one small AC unit in the living room. This is probably not an issue when the evenings are pleasant and you can open the doors, but we were there right after a tropical storm moved through, and it was very muggy. The front bedroom especially would be very hot if you tried to close the door and wasn't much cooler with the door open. We were able to adapt and still really enjoyed our stay. This is just a comment for hot sleepers (like me) to be aware of and prepared for.
