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.

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.

Beautiful location / would visit again.
FANTASTIC stay. My only complaint (and it could just be ignorance on my part) is that the first night you could have hung meat in our room it was so cold. I didn't realize at the time how to adjust the temp with the system this resort uses. I figured it out and the rest of the stay as far as the temp goes was perfect. The location was perfect and just stunningly beautiful. The parking spots were pretty tight - if there's anything that the resort coud improve, I would suggest that.
