My boyfriend and me spent 4 nights at the banyan tree sanctuary and it was really a wonderful time. It is a peaceful and inspirational place where you can meet interesting people in the common space, enjoy the nature in the beautiful garden and do yoga class or massage (for extra charge). We stayed in the suite with nice ocean and sunset view where we had a private kitchen, bathroom and a balcony. The room is clean and comfortable but there are often bugs and geckos - for us wasn't a problem, but you should be aware of this. Although the place is very quite, you are in the perfect position to reach kona center and to explore all the island. They ask you to leave the car outside in another road (for check in and check out you can enter and park in front of the room). it is ok but after the sunset there is no light and you need a torch. A nice surprise was that gave us some of the fruit from their organic farm.
A special thanks to Maggie and Benjamin who made our stay there even more special.
