Great property.
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.
Beautiful sunrises

good location, needs a refresh
Grab & go breakfast was convenient and the location was good - near grocery store and restaurants with an ocean view. Our room, however, was quite run down and even though I reserved a king bed, we were given two doubles with no other options available. Isn't that what a reservation is for?

Peaceful Place On The Ocean
Thus is a nice place right on the ocean. If you are looking for peace and quiet, this place has it. It did however seem pricey for what you get. The complementary "grab and go" breakfast was lacking. They did not have any hot coffee available. We were surprised by that as were several of the other guests. When asking about it at the front desk, we were told to use the coffee maker in the room. I tend to avoid those things as I have seen some pretty grungy ones over the years. Their coffee maker looked clean, but we opted to walk down the street to Starbucks.

The staff was so friendly. One of them even gave us her personal beach chairs to take out for the day. They have bikes available for free for day use as first come first serve. Property is beautiful and area around it has LOTS to eat/shop/ we had a car and it was perfect central location to see the whole island! Will definitely stay there again.

James, 2-night trip

10/10 Exceptional

Clean room, it has basic amenities, big bed although it was a bit stiff for me but it was good enough for 2 nights nice view of the pool/ocean and sunrise. Restaurant has great food. I love the free artichoke dip it was the best Mai Tai was really good not too strong alcohol. My main course was their special Spinach meatless wrap and it was excellent.

Average
Property was probably about as expected for the price. Pros: - Right on the beach - Continental breakfast - Bikes are available for free Cons: - We booked for two people, and they gave us two double beds instead of a queen or king. That didn't make sense to me. The default should be one bed. There were no options to choose beds when I booked. I don't know if that was an ISO problem or a hotels.com problem. - Property inside and out is very old and dated. It does not look like the picture. Rooms smell very musty. - Television was basically broken
