After our week-long stay at the cottage, my wife and I felt that it was the perfect embodiment of life on the Big Island. The property just FEELS tropical, with its openness and integration with the lush, natural landscape. From the cottage, you have a beautiful, unobstructed view of the ocean, and the yoga deck is a great place to relax and take in the sights. (We were a tiny bit bummed that you can't see the sunset from the cottage, but on one of the nights Peter graciously let us watch it from his own lanai.)
Barbara was not there during our trip, but Peter was one of the most welcoming and gracious hosts we have ever had. He was always willing to lend advice when we needed it (and offered plenty before we even asked!), but at the same time was respectful of our privacy. He is incredibly knowledgeable about the island, having lived there for many years, and his suggestions were always spot on. From time to time, he would generously bring us avocados and bananas from his trees, and encouraged us to pick any of the cherries, limes, or other fruits growing on the property.
The location was perfect for what we wanted: quiet and secluded, yet a short drive away from some of the best snorkeling spots on the island, as well as a grocery store, a farmer's market, and a surplus of delicious restaurants. And if you would like to go into town, Kona is only about a 20 minute drive away.
I will make two small notes that are worth keeping in mind before booking. First of all, this cottage is very "organic", surrounded by tropical nature. While this is one of the most attractive things about the property, it also means that you are always surrounded by little "friends", including roosters crowing at 5am. We were never bothered by it, and in fact thought it was entertaining to watch the geckos, but it's a good thing to keep in mind if you aren't used to that. Secondly, this cottage is fairly close to the other two properties—the other Airbnb cottage and Peter's home—to the point where you can hear conversations in either building. We never felt that this was a problem for us personally, but we were a little bit surprised by the proximity.
Having said that, we absolutely LOVED our stay here, and would highly recommend the cottage to anyone looking to get immersed in the Big Island lifestyle.
