This is a wonderful find on every level. The apartment is connected to, but totally separate from the main house. My wife and I stayed in the main bedroom, and our daughter slept on the pull-out futon, which is also the same room as the kitchenette / TV (not that we watched any TV, but still.) We made breakfast every morning (I would blend juices from local fruit, including some that came from trees on the property) and ate out on the patio where a gecko named Thomas would visit us looking for food (he was definitely not shy!)
You fall asleep to the sound of coquis and wake up to roosters... it's a wonderful spot, and Allen & Dianne are really friendly and offer lots of great advice for where to go. We appreciated the local chocolates and macadamia nuts they gave us... honestly, a perfect little spot in a sleepy part of the island full of volcanos, waterfalls, and lava tubes.
