We stayed at Pono Kai in the beginning of January this year, and we loved it. It is not fancy and some of the furnishing/amenities in the condo itself were a little older and worn at times but we did not have any problems with cleanliness, ants, or our a/c.
The pool and hot tub were great, and all of the grounds were really well maintained. They even have nice Weber gas grills around the property for guests to use, as well as an herb garden where you can go to get fresh herbs to use for cooking. We didn't really have to deal much with the front desk so I can't speak to that, the activities desk was fine to deal with. We had told them we found a cheaper rate for one of the activities online and they were happy to match that price.
The resort is located pretty centrally on the island which made getting around pretty easy. We loved walking along the walking path along Kappa, we would do it in the early am and sometimes we would do it again in the evening to hit up a happy hour someplace in town. The beach is right at the hotel, the water there is clean and calm enough for swimming. The beach itself is the town beach and can be a little dirty, but all things are relative. It is right near the public boat launch so there is a lot of rope, and parts of buoys there but nothing compared to dirty beaches in the Northeast (which is where we are from), no broken bottles or anything like that. The sand right by the water is clean and we never had a problem finding a clean area of sand to set up camp in.
So, overall we had no problems. The place is nothing fancy, but it is comfortable, in a good location, and has great grounds.
