ISO was so close to the ocean, you can walk to the ocean from ISO. The ocean view room was so great and amazing, the breezy was great. The pool was large one side is 8 ft deep. The sunrise was magnificent every morning. Shopping is one block away by walking or driving. Very quiet and relaxing.

Nice swimming pool and firepit, lounge chairs on lawn oceanside, onsite restaurant and lots of nearby dining and shopping, great walking/bike path with bikes available at the hotel, good 'grab and go' breakfast with tables available if you wanted to eat there. Small refrigerator in room, no microwave.

Likes: ocean view from the rooms, centrally located between North and South points of interest on the island, proximity to shopping and eateries. Dislikes: only restaurant on grounds opens late afternoon, pool needs better lighting and repairs, hotel is old and dated. We made reservations 2 months in advance for our honeymoon for a weeks stay and a special request for ground level room and king sized bed (which we specifically reserved), and were ignored. We were instead told to "just push the 2 full sized beds together" on our 2nd floor room. I overheard other guests with similar concerns which were also ignored in favor of other guests staying shorter periods of time. Even after requesting a room change the next day and explaining my wife's difficulty going up stairs, we were told that we could move to the 3rd floor room with a king sized bed or stay in our current room. The lack of consideration for special requests and customer service has lots of room for improvement.

When you arrive at the hotel, the front desk looked like two old military desks and could’ve been way more inviting with Hawaiian music playing instead of the modern rock that was playing. We arrived early and it would have been nice to have a safe place to store luggage while you wait for your room. The walking path and bike path allows you to walk and bike to shopping. There are free bikes that you can pick up at the hotel. Most of the hotel staff was great however, the very first person we came into contact with and one that we came into contact most did not have that aloha spirit and seemed to be grumpy most of the time, The pool area was nice, but the outside planters weren’t planted, and there was no little bar anyway to buy drinks to have by the pool bushes. The patio furniture was kind of old and thread bear. Overall was a very nice place. A nice quiet neighborhood. The rooms were clean and comfortable.
