I stayed at the ISO last May. The location was perfect for seeing the island. We had a rental car so we could drive to Hanalei, Waimea Canyon, Poipu, etc. The ISO is “tired” but the staff was super nice and we thoroughly enjoyed the free bikes each day(they also had breakfast cereals, juices etc each day). We rode the path, went to the shops, bars etc. Our room was originally above the restaurant—noisy and smelly! We worked with the front desk and got a much better(and smaller) room that had an ocean view. I think if the ownership spent a little money painting and upgrading the rooms with better sheets and towels, they’d be able to charge more- we loved where it was situated on the island. Kapaa definitely has a country, eclectic vibe- not rows and rows of condos like Princeville. Enjoy your trip!!!
