This location is remote - it is 1.5 hours south of the Kona airport, one hour from Volcanoes National Park and 30 minutes to the nearest market. If you are looking for a resort town with all the amenities, night life and tourism, this may not be your rental. But the allure of this one is in the loss of those things - this house has quiet, beautiful views and space for you and yours.
The owner lives elsewhere and the caretaker lives just up the street - he is a positive character and full of stories of the area and what being in Miloli'i is like (this rental is not in Captain Cook proper, but a small fishing village further south). Be expected to hand him $20 when you get there, it is a deal that the two have about the house being rented out that the owner messaged out before heading there.
We slept 11 in the house easily during our visit -
Second floor: Master bedroom with a king bed, spare bedroom with a full bed, pull out couch with another full sized bed. Full kitchen, bar dining. Massive porch with ocean views.
(There are no internal stairs between floors, all traffic goes outside to the patio stairs)
Ground floor: Game room has a full size bed and twin-sized bunk beds. Bedroom with a full size bed and an air mattress.
There are also all the ocean swimming gear you may want to use, all in different levels of quality. There is a snorkel spot nearby that is good to jump into, and a public beach that is a 10 minute drive and 15 minute walk that is beyond worth spending some time at since the location is so isolated.
