Liked: Cleanliness, staff & service
My partner and I stayed August 5-10. It was the most relaxing 5 days we’ve had in a long time. The staff was friendly and helpful and the property was perfect. We had an ocean view and we could hear the waves crashing on the wall. I loved the roosters, hens and baby chicks. They roamed all over the place and doodle dooed through out the day. We didn’t have a car to get around so we pretty much stayed around the area we were staying at. Best time just relaxing and enjoying the beautiful scenery of Kauai.

Peaceful boutique oceanfront hotel. Perfect for watching sunrises and for relaxing in the pool in late afternoon after a day of outings.

3/5 Okay

Traveled with partner
Disliked: Staff & service, amenities
The location is great and accessible to all parts of the island. The rooms are updated and nice. However, the staff seemed inattentive and the amenities were limited. Some of that is due to COVID protocols, but we felt like we the lack of services (room cleaning, breakfast, etc) should be made known ahead of booking.
