The ISO is amazing to stay at while visiting Kauai. Fresh fruit and snacks daily, the ocean views, pool fun and close to shops. The staff is incredible. The best was being able to watch the whales from our room. Second year in a row for us and can't wait to return.

The staff was great! But the water in our shower was lukewarm at best, and when we turned the nozzle all the way to hot it actually got colder. The sink was fine and had hot water. The grab and go breakfasts were just ok.

The grounds are stunning, the pool was well maintained and ocean views are breathtaking. The staff were attentive and helpful. The rooms are comfortable and clean. The location is great if you are planning to spend time on the north and south shores, helps reduce driving times if you are planning to be very active!
