Such a nice getaway my husband and I had at the ISO. From our room we could look out at the pool and beautiful ocean. Super comfy bed and pillows. Great size room. The staff is super nice and helpful. So friendly too! I will definitely stay there again once I get back to Kauai

Loved the ocean view from my room. The room was clean and staff was super friendly and helpful to all my questions. Most importantly to me was that the walls were thick or insulated enough that i couldn't hear any of the adjacent neighbors through them.

Excellent location very nice staff , our ac unit was faulty However with it only being a 2 night stay it wasn’t worth the hassle, they were extremely friendly I’m sure if I pushed the issue they would have dug into it, also was fully booked

The rooms were clean but the property is run down in a few areas. Customer service was good but one of the ladies at check didn’t appear to like her job. I don’t have her name but she was the middle aged blond lady. Everyone else was wonderful.

Correct pour le prix, bien placé + parking gratuit

Nous étions au rez-de-chaussée avec une vue sur la piscine. Le petit déjeuner, n'était pas du tout ce quoi nous nous attendions, muffin, lait au chocolat en briquette. Le café/thé devait se faire directement dans la chambre. La chambre en elle-même était correct. Mais nous étions vraiment bien placé et point bonus le parking était gratuit.

Really loved views of the ocean suite, nice grounds & beach next door was never busy. As others mentioned, our King reservation was not guaranteed so we almost ended up in a double. Be sure to call ahead & confirm what you expect. No coffee in the lobby available, not even during the grab & go breakfast. Small in-room pot only. Nice perks of sunrise yoga, and having bikes for use as long as one is available that is your size since the seats don't adjust. East parking. Great spot to explore Kauai by car, would stay here again!

We only stayed here a short time, but the rooms were clean and functional. The pool is nice for lounging. You can get free bikes in the lobby; the hotel is near Ke Ala Hele Makalae Path, so it is really easy to go for a bike ride along the coast with your family. The hotel has a sea wall so you can't get into the ocean right in front of the hotel, but you can access the beach and walk on the sand at the two neighboring resorts.
