Bldg 20, specifically unit 20-203 Has a Cockroach infestation. What was supposed to be a relaxing trip to celebrate our 10 year wedding anniversary ended up being an exhausting week of sleepless nights and long days out to avoid being in that room. This was our second time in Hawaii. The first time we came to big Island we stayed at the Royal Kona..no bugs. This time we stayed at Kona Coast Resort. I can say that when we first entered the unit I was pleasantly surprised. The unit is like a small 1 bed room 2 bath apartment. The bed was extremely comfortable and the wifi worked just fine for running 3 devices at once. It appeared to be clean. The shower was not cleaned properly though. The shower had a overwhelming bleach smell and the shower floor was slimy. The dishwasher was running when we arrived....it had no dishes in it...kinda weird. The ice maker is obnoxiously loud and made 3 ice cubes all night despite all the noise it made. The front door has a large gap that you can see A LOT of daylight through. The laundry machine works but it probably needs to be cleaned. No Keurig coffee maker, just a standard coffee pot. I expected to at least get 100% Kona coffee...they only give out a 10% Kona blend...I can get that crap anywhere. The unit was fully equipped with all kitchen and dinning cookware and utensils. Too bad the coaches are on everything. We washed the items before use and only cooked once during our stay. We decided it was best to keep food out of the room as much as possible. We had some ready made ribs from the grocery store one night and put the bones in the trash...not even 5 minutes later there are 10 roaches in the can. I ended up buying a can on Raid on day 2 after I read reviews I hadn't previously seen on the roaches. They were all over the counter and coming out from under the cabinets in the kitchen. I saw a dead squished one on the wall in the bathroom that was missed by the cleaning crew. I had trouble sleeping the entire time. I couldn't help but think they are going to be crawling on me while I sleep. Fortunately I only actually had to kill one in the bedroom but I had already sprayed the perimeter of the entire unit inside and out including around the windows and doors with Raid. If we had any trash that couldn't go out right away it was bagged and stored on one side of the refrigerator so that the bugs had no reason to come out from wherever they were hiding. I can say the pools were nice, the bar/restaurant food wasn't bad (just expensiv) and my husband said the Mai Tai there was the best of everywhere else we tried them. The botanical walking path was nice. The walk-ability is not ideal for people who want to be able to explore shopping , beaches or restaurants on foot. This place is a time share and they will offer you the world just to go to an owners seminar and call you multiple times a day for weeks until you just give up and change your number. We did not attend nor do we ever want to own such a disappointment. I have notified the director of tourism that I'm definitely not coming back. I did not fuss about anything during my stay. According the other reviewer that did reach out to management they were either moved to another unit with bugs or told there isn't anything that they can do "it's Hawaii, we have bugs" ummm I live in Florida...we have bugs.. OUTSIDE. I'm disappointed that a state that depends on tourism to thrive is going downhill. I definitely didn't feel the Aloha spirit at the Kona Coast resort. I might as well have been at a cheap hotel in Chicago Illinois.
