This house is definitely off the beaten path of Kapa'au! We recommend following Hap's helpful and accurate directions to the house, as Google Maps had difficulty with the address. The house is pretty sticky, but the ceiling fans cool it off quickly. The house and surrounding vegetation is beautiful, and Hap's guidebooks/magazines offer a nice range of suggestions for the area. We experienced safe wildlife indoors (a couple geckos, millipedes, and a cane spider), which some mainlanders may want to consider.
Hap is very friendly and communicative, he called us a few hours after we booked to say aloha and offer a few more details, and then a few times in the week before to check in. The house is a quick 10-15 minute drive from the beautiful Pololu Valley (highly recommend this hike, even in the pouring rain!), and Kapa'au and Hawi are close, but most other guidebook-type spots are at least 30 minute drive. For the steep Pololu Valley hike, we highly recommend using one of Hap's well-made walking sticks on the front porch. There were a couple cars in and out of the driveway and sheds in the yard during the day, so be aware that others may be around (we assumed visiting Hap's woodworking shop).
