We really enjoyed our stay at the ISO. The hotel met our needs for our 4 night stay. It is centrally situated so it was easy to explore. Clean rooms, comfortable bed and super friendly staff. Good dinner restaurant on property. Good selection of continental breakfast foods. Amazing sunrises! We would stay again if we come back to Kauai.
