The Tiny Red House was a great base for our trip to Kona for the Ironman World Championship.
Although it has 6 comfortable beds, do be aware that it is a very compact set up. The hosts are entirely upfront about this. If you are planning on visiting as a group, would that group be happy to share a tent, or a caravan, or a small sailing boat? The accommodation is similarly compact and intimate. But for 2-3 adult close friends, or a family of 3-6, it's great! The location has really comfortable night time temperatures, and is just far away enough to escape the hurly burly of Kona (15mins by car).
