Waipio Hostel is a extremely cute and practical place to explore Pololu and Waipio from. We especially enjoyed our visit to the Hawaiian Vanilla company which is near by. Everything at this hostel is clean and the bed is very comfortable. Cooking in the outdoor kitchen might be the highlight of the trip for me. You will hear quite a bit of noise from above and the walls between the rooms are quite thin so we could hear the other guests. This hostel is reminiscent of camping for me since it is so open and airy. I would recommend this to others.
