Excellent cleanliness and attention to details, loved the mineral onsen provided for guests.
The breakfast is an amazing spread of healthy options (very typical Japanese breakfast foods) for a great price (when breakfast was added as an option through hotels.com - it's double the price if you buy on-site).
The free airport shuttle is really awesome as the location isn't that near the Yui monorail (which is probably going to be the only public transport most people would take in Okinawa), but is extremely close to the airport by car (takes 10-15min, so shuttle can go back and forth many times throughout the day).
Rooftop area is also nice, offering almost 360 degree views of the surrounding areas and nearby ocean. Check-in/out is also automated through self-check-in kiosks which was fast and efficient.
Only downside for some might be that the location isn't as central or close to the Yui monorail, however is still walkable (budget ~20min+) and make sure to choose the right roads and sides of roads to walk on to optimize the path, especially near highway 58, which you need to cross overhead walkways to reach the Yui monorail and Kokusai-dori on the other side, and account for the way traffic lights there can take several minutes to change unlike in North America. Based on what this hotel offers, it would probably cost at least double per night if it were more central.
