The pool and grounds were wonderful.
Free continental breakfast - especially for fresh arrivals - was a hugely appreciated.
The free bikes were also a terrific treat, especially as the oceanside bike path is just around the corner
Not a resort. Clean, good price, no frills, fantastic view,quiet and convenient location. We would stay again. Hotel should add in room safe and desk. Clean and no pests. Kept lanai door open to listen to the crashing waves at night. Beautiful sunrises every day. No elevator so beware if you are a senior. Housekeeping with 24 hour request. Needs cosmetic work bit otherwise great!
Yoga on the beach every morning 7-8 was wonderful and the bikes in the lobby were free to use. Ver nice property, I really enjoyed my stay.

Needs better breakfast options.. the “L” rooms need to do something about the giant beams that run thru the room and block the closets..

Disliked: Property conditions & facilities
I wasn’t aware that our room was above the restaurant on the property so we heard the music from downstairs up until the restaurant closed. We also had a couple next door who were fighting loudly on one night, which made it hard to sleep. The room was clean though and we enjoyed the complimentary bikes which we took out on the Kapaa trail. I also liked the location next to the beach.
The staff was so friendly. One of them even gave us her personal beach chairs to take out for the day. They have bikes available for free for day use as first come first serve. Property is beautiful and area around it has LOTS to eat/shop/ we had a car and it was perfect central location to see the whole island! Will definitely stay there again.
