Todd makes this AirBnB amazing: he is a smart, generous, fun host, who is a major resource in knowing where to hike, sail to see whales, dolphins or fish, eat, snorkel, surf or dive. There are plenty of amenities in terms of cooking, washing, or surfing. He's clear on cleanliness standards in the air bnb in a pleasant way, which is a positive. His AirBnB is sunny, modern, quiet, well-ventilated and -equipped, and the bed comfortable. There are fitness classes and a professional gym 5 minutes away if you're into that, as well as a top local cafe.
By car, Hawaii Kai is about 16 minutes from Kahala, and 20 minutes from Waikiki. This is nothing for US Mainland distances, but a bit far for Hawaii. Make sure your car isn't a gas guzzler. Traffic isn't bad getting in and out of "town".
On the other hand, ToDD's AirBnB is close to Koko Head, Hanauma, Sandy's, and many other great nature spots compared to Waikiki rentals. Costco is also close by; and plenty of quick, diverse, good and affordable food for take-out. Enjoy!
