Waianae is on the West coast, leeward, which is drier and less windy and less waves. If you're a snorkler or diver it's angreqt location. This part of the island is less developed and things are mellow. There are some great beaches - we went snorkeling and surfing (beginners). We also visited many other spots around the island, the driving from waianae was lengthy due to less developed road system.
The condo was great, provided ample space for a couple. It was overall very clean though some upgrades (kitchen) would be nice. Checkin was very easy, on site staff very friendly and helpful, the information provided by the host was detailed and accurate.
I can recommend this place and the host.
