Overall, a very good experience! Jason is a supershost for a reason - we had some issues upon checking in and he was highly responsive on everything.
The location to downtown Kona is superb, which is why we stayed. As he says in the description, the condo is old and reflects it in certain aspects like sloping floor in the bathroom, old windows and locks, and the cleaning level was a bit subpar in my opinion, but I also understand you can only get old surfaces so clean.
The amenities provided are very useful: beach chairs, cooler, towels, snorkel, sunscreen (we forgot ours), outdoor seating, vinyl records and a well-appointed kitchen.
Be aware that the bed is super squishy, so if you prefer a firm mattress, this isn't it. Also, there is only A/C in the bedroom and you'll want to turn it on and shut the door for at least 3 hours prior to bedtime, otherwise, the bedroom will be hot. The bathroom door doesn't stay open so you tend to run your rump into it.
