Rare find! I am originally from Oahu so I know the area well returning 2-3 times per year. Never have I experienced such gracious hospitality, physical comfort, squeaky clean everything, and little touches that make your stay easy breezy.
Location: it doesn't get better than this! We didn't use our rental car the entire stay. A few minutes walk to Kailua Beach Park (this is the beach you want, not Lani Kai trust me). The other direction a few minutes away is the main shopping plaza with Whole Foods, coffee shops, restaurants, etc...
Comfort: The studio is a lot larger than the photos. The bed has a quality mattress. Kitchen well stocked. Bathroom water pressure and hot water is divine. WiFi dependable and fast!
There is a front porch area to sit as well as a cozy back yard picnic bench.
Honestly if this is your price range, you will not find a better value. I rent the luxury homes on Lani Kai beach for my groups going for $10k per week and this studio was better equipped than most of those houses with little thoughtful items.
