This house was super close to Kailua beach, (like a 3 minute walk to sand, another 2 to water), and also an easy walk to Lanikai beach (an easy mile, which trail/sidewalk the whole way). It was also close to town, two farmers' markets, and lots of restaurants. The house came with boogie boards and other beachy equipment, plenty of towels - both for at beach and at home - and an outdoor shower to rinse off sand before going in the house. The kitchen was fully stocked with pots and pans as well as all the condiments we could ask for (oil, butter, seasonings, soy sauce, etc.), saving on us having to buy all the things just for a week of food. The owners, who live next door, were very kind and responded quickly to our questions.
There were five of us - three kids (6, 8, and 10) and two adults. The house was a great size for the five of us, and there was always enough hot water for our post-beach showers.
I can't think of any complaints, and we will definitely try to stay here again if/when we're ever back in the area.
