After extensive searching, our family agreed on the " Peaceful House in Kona", Captain Cook, which turned out to be a great choice. The house is large and quite spacious. You can read the fully accurate details on Airbnb without my repeating.
Guy, Delphine's father, met us upon our arrival, providing information that day and throughout the week on the house, shopping, beaches, and the island in general. He seemed to enjoy imparting facts and info as much as we enjoyed receiving it.
My wife and I took the master bedroom; my son and daughter took turns alternating between second bedroom and living room couch.
We spent most of our days/nights "on the road" doing the tourist thing but did use the compete kitchen for the occasional meal. Early mornings were spent on the fully screened porch, drinking coffee, enjoying the ocean views, watching the animal life, (including wild pigs) in the yard below.
Not a criticism but just an observation; if someone in your party has mobility issues, be aware this house is located on an extremely steep hill which also accounts for the terrific ocean views. The long driveway has to be close to a 40 degree slope, The road down to the two local beaches is also quite steep. The beaches in the Kona area are inclined to be somewhat rocky (lava!) generally; however those located in the bays provide great snorkeling. An added bonus is that equipment for this is provided by "Peaceful House". Our favorite beach adjoined a National Park called "The City Of Refuge"
We usually alternate our Hawaiian island trips between the various islands, but when we return to the 'big island', we will certainly consider "Peaceful House" again.
