Please remember the following description of our hotel experience: We had an oceanfront view from the second floor, facing the pool, and enjoyed some privacy thanks to the nearby trees. The room was clean and comfortable. The hotel's location was convenient for heading north, south, and to the west shore, and we had many activities scheduled. The hotel offers a fantastic sunrise view but could use nicer and more comfortable beach chairs. Although the beach in front of the hotel may not be the most beautiful, it was good enough for a morning or evening walk. There was plenty of parking available, and the pool was nice, clean, and had enough chairs. There was also a small fireplace where we could hang out after dinner. The breakfast was grab-and-go style, which was fine for us. Bonus is the yo Ga class at 7 AM, the instructor she is super sweet and great!

Very nice hotel in a comfortable location, easily accessible with the car and with some options within a walking distance or by bike (available in the hotel to rent). The room was fully equipped, including a fridge & coffee machine. The hotel provides refillable bottle & a purified water fountain in the hall. Amenities and enough clean towels were provided for our 3 nights stays, if more needed you can ask the reception. However worth noticing they don’t have daily cleaning service, but rely on DIY services providing you with the resources to ensure a clean room & nice stay. It was surprising but we actually appreciated it as a way to reduce waste & understandable with the min staff they have. The Grab & Go breakfast is a nice concept that allowed us to enjoy beautiful sunrises from the room or the beach.

Carmen

Loved it! Near the airport, restaurants, and a good distance from all the places we wanted to adventure to. The free bikes were great, right next to the ocean, the restaurant was very good too. Also, the front desk ladies and housekeeping were all great (especially Anna) you don’t get housekeeping, but if you need anything, they’re good providing what you need. There’s some reviews that stating that smells moldy, I didn’t smell that, but I can see the outside halfway carpet duty, but the hotel is right next to the beach, it rains almost every day and everyone is walking by with their muddy shoes.

Paola

Good location, right on the beach, our room was a decent size, pretty quiet (except for the ocean waves crashing on the beach right outside!), had a fridge and quiet A/C unit plus ceiling fan, a big screen TV, comfy king bed. We didn't use them this trip, but they had free bikes and yoga classes, decent restaurant on site. Grocery store, restaurants, pubs, and other amenities within walking distance. Rented kayaks from Bring Me A Kayak just up the road to paddle the Wailua River and hike to the falls -- great!

Keith

It was a great stay (stayed in a ocean view room). The room was big, clean, had coffee marker and fridge. The views were spectacular. The common areas were really nice and the pool too. We would stay here again. Parking was easy. Front desk was friendly. They offer free grab and go breakfast (not much not even coffee but the pineapples are great) and free bike rental and there is a nice nearby bike trail next to the condo.
