This apartment on the beach is a great way to escape the bustle of Honolulu and see a quieter side of the island. Looking out over the ocean from the lanai, you will almost certainly see a turtle if you look long enough, and can snorkel and see them up close as well. During our stay over Christmas, the half mile stretch of beach in front of the building was never crowded, with usually 2-3 families splashing in the water or sunbathing.
You'll also be near lot of delicious food trucks in Windward Oahu, with the North Shore being a bit further but very accessible, compared to staying in Honolulu.
