Everything was perfect. The villa was clean and quiet, with plenty of supplies for the 6 nights we stayed (dish soap, laundry detergent, shampoo, toilet paper, etc.). There were lots of beach chairs, towels, umbrellas and a cooler for us to use.
Check in/out was fast and easy- they even had our room ready early so we could check in earlier than expected. They answered questions quickly via text and were very communicative throughout the process.
The pools were great, the beach was gorgeous and not crowded, despite it being spring break. There were wonderful restaurants just a 5 minute walk away at nearby hotels.
My only complaint (and it's not about the property itself) is that Ko Olina does not allow beach umbrellas or tents for shade at our lagoon. But there are several palm tree clusters that you can find a shady spot under.
All in all, everyone loved it, even the most picky of us, and we would definitely stay again if we go back to Oahu.
