The accommodation was perfect for our short stay in Waipio. Unfortunately, we weren't able to hike into Waipio and Waimanu as we had originally planned due to the dengue outbreak, but it was still a nice drive from the apartment over to Pololu valley to do the Pololu-Honokane Nui hike. The apartment is great if you're looking for a quieter stay away from the hustle and bustle of some of the bigger city/towns. We didn't meet Bill, but his instructions were very straightforward and easy to follow. I was initially confused when I read the rental agreement (portion about credit card info), but that was a mistake on my part; review the "Other things to Note" section of the airbnb listing - it indicates that the credit card info isn't required if renting via airbnb. I would definitely recommend this place to anyone looking for a base if doing the Waipio-Waimanu valley hike (once it's open again).
