Nice for the price but not luxury
The ISO is a great budget-friendly hotel in Kauai. Its right on the beach so the location is great and the rooms are very comfortable. There is no AC but that didn't bother us with the ocean breeze. The fridge in the room was large and we stocked it with beverages we enjoyed on the balcony over looking the ocean. There is no beach to swim (its very dangerous here) so you will need to drive to another spot. The location is great in terms of grocery stores, restaurants and dessert shops, and even an ABC store all in walking distance. The breakfast is OK and gets boring after a few days, and the staff are not nice at all! Considering they are working in the service industry they are very rude and seem bored and bothered if you make a request. There is also live music every night at the restaurant that can become annoying. However, for the price and location I would stay here again.

Overall, below average...not one or two big issues, but many minor problems, tv difficult, room not ready at check in, breakfast weak, coffee maker useless, cleanliness adequate, parking at night awful, etc

Excellent value
Overall an excellent value for the price paid. Seems like every room has a view of the ocean, which was beautiful. The free breakfast was serviceable. Room was clean and comfortable. Just wish the pool was heated (it was quite cold). The shower was lukewarm and lacked pressure. But the staff were all super friendly, the location was good, and the price was excellent.

The ISO is a decent hotel for the price point. Rooms are nice with a view. There’s really no beach access from the resort but there are some close by. Yoga every morning at 630am was a nice bonus. Restaurant on the resort is good with a great happy hour. We didn’t stay at the resort much as we wanted to explore the island but for what we paid, it was totally reasonable. Continental breakfast was not the best, did not like the coffee.

Overall - OK
Overall we enjoyed our stay but there were a few things keeping me from giving this a great rating. First the good - the resort is quiet and the grounds are very nice. The view of the ocean is great, with at least a partial view from all of the rooms. Beach area was small but nice. Breakfast was minimal but adequate. Staff was friendly. Now the bad - We wound up with what was probably one of the two worst rooms at the facility. Right across from the laundry so we couldn't leave the door or windows open in the mornings because of the sound and the smell from the dryer exhaust. Our room had a tree blocking most of the view of the ocean so our primary view was the rotting wood around the pool mechanical shed. If you stay here, make sure you do not get stuck in rooms 114 or 214 or this will be your view and experience. The rest of the rooms are probably better. The rooms were clean for the most part but throughout our stay, they used a broom to clean our carpet and we never saw a vacuum. Not sure if they do vacuum the rooms or not but they didn't do ours while we were there. There were also dirty coffee cups in our room that they never took or cleaned. We had our own so it didn't matter that much but it didn't give us a good impression of the cleanliness of the room. Overall I would still consider staying again but definitely in a better room. The price was fair and the central location is great.

Fair 4.0
Disappointment from beginning to end
We had to leave this place during our stay because the pool was out of commission, there were more bugs than I care to describe (combination of termites which we were unaware of but were told there wasn't anything they could do about it, mosquitoes and some other flying insect). I understand things can be out of the hotel's control, but upon switching to a hotel less than a mile away, we no longer were faced with that problem.

Central and clean.
Very central, clean and comfortable. Absolutely can’t swim or snorkel due to rocky barriers. Breakfast is ok with fresh fruit, toast and oatmeal. Will come back.

Don’t stay here if you wanna have good breakfast
The room was super clean and had a nice view. We had to sleep with the windows open because there was no AC. It was raining so I didn’t miss the AC but I believe the room would get hot on sunny warm days. Breakfast was very simple. We had to go buy groceries to be able to have a decent meal on the morning. A lot of the other guest were doing the same. The hotel is well located. There is a lot of restaurants and supermarkets near by (walking distance). The pool is cold and saw nobody using it. And the beach in front of the hotel is not the best. You’ll want to drive somewhere else to have a nice beach to relax. They offer bikes for free and you can ride on a bike path that near the hotel by the coast. (The bikes are not in good shape but it’s free right?)
