Our family of four ( 3y/o & 7 y/o) LOVED our trip to Kailua and our time at Shari's. The sleeper sofa was super comfortable (I think that might be the first time I've ever said that) and the bedroom very nice as well. The kitchenette was perfect for breakfast and light lunches. We could enjoy some adult time in the living room or on the deck when the kids went to sleep. Shari was great about providing extra towels and we took advantage of all the beach toys, boogie boards and chairs. We were able to visit family staying at Bellow's Air Force Cabins, drive up to the North Shore, visit Waikiki (and run the Hapalua Half Marathon) and explore the restaurants / shops around the neighborhood.
We live in Chicago so used to traffic and city noise. The road outside does get busy, but calms down at night and in the morning. Navigating the drive way can be a bit tough with the road being busy ... but nothing we couldn't figure out!
