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.

8/10 Very good

The pool and grounds were wonderful. Free continental breakfast - especially for fresh arrivals - was a hugely appreciated. The free bikes were also a terrific treat, especially as the oceanside bike path is just around the corner
Michael, 1-night trip

8/10 Very good

The location was good. While it is an older property, it was clean and comfortable. Free grab and go breakfasts were great and a big cost saver. While no gym, daily yoga classes were lovely
Chukwuemeka, 3-night trip

4/10 Fair

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?
Stephanie, 5-night trip

10/10 Exceptional

Yoga on the beach every morning 7-8 was wonderful and the bikes in the lobby were free to use. Ver nice property, I really enjoyed my stay.
