We had a wonderful time at Kai's place. I would have actually liked to stay longer, but got chased away by a hurricane alert. Both Kai and his dad were very helpful assessing the conditions, being reassuring and giving us the kind of wise advise that only veteran locals can offer. The apartment itself is cute. Even in hot/humid weather the air circulation is great and we didn't need to use the AC. It is very close to the water and the bay offers outstanding snorkeling and wildlife viewing opportunities. We rented a couple of SUPs one early morning and were treated by a pod of dolphins checking us out! :-) The only thing I regretted not bringing was good bug spray. The lush vegetation in the area means TONS of mosquitos. Overall, Captain Cook is one of my favorite places on the Big Island and Kai's apartment is a great home base while exploring it. Thank you for your hospitality!
