My wife and I stayed in this condo in the Beach Villas for a week. The Ko Olina area is just stunning, and the Villas sit alone on one of the four coves, so the beach was never very crowded. It's a short walk to the shopping center and 5 minutes to the Four Seasons, one cove over, if you want to have a fancy meal at La Hiki. It's also an easy drive to Honolulu. We visited Iolani Palace, Diamond Head, Punchbowl Cemetery, Pearl Harbor, and many other attractions.
The unit itself is very comfortable with a large lanai. Beach chairs, cooler, and other beach accoutrement are available. The kitchen is nice with very high end appliances. Overall I felt it was well worth the price. My only suggestions for the owner would be to upgrade some of the smaller appliances and utensils. First of all, please sharpen all the knives. If indeed the kitchen was designed by Roy Yamaguchi, he'd want knives sharp enough to cut into a pineapple. I'd also suggest providing a scissors and cheese slicer. There's a very nice wine fridge, which we didn't use, but I was disappointed that there wasn't a cocktail shaker. Lastly, please upgrade the paper products - using the cheapest one-ply toilet paper, kleenex, and paper towels detracts from an otherwise gorgeous unit.
We had a wonderful stay at the Beach Villas. I'd give it a solid A rating. A few small investments would make it an A+.
