Kenneth's place is great! The sun room across from the kitchen is magical and would be a great place to spend a day if there weren't so many things to checkout on the island. The full kitchen saves you from eating out every meal. There are ample windows and screen doors to enjoy the warmth of the day or coolness of the night.
The location in Captain Cook is superb. Only ~15min away from Nāpō’opo’o Pier for a kayak/snorkeling tour and Two Step for more snorkeling. Kona is an easy 25min away and it is minutes away from a grocery.
Kenneth is on-site in the main part of the house if any questions or issues arrive. The guest quarters are under the main house with its own private entrance. You do share a ceiling with their floor, but noise or privacy was never an issue.
I highly recommend it!
