I arrived to the location about 2 hours earlier from check in time, But the cafe at downstair was open and let me checked in. Staffs were friendly, helpful and fun to talk. You can get discounts or free drinks from the cafe restaurant. I think the hotel location is really convenient to access to anywhere in the island.
Also, it's the best place to explore deep Okinawa city atmosphere that is not in tour book. So if you wanna enjoy your stay as a local, this hotel is the perfect to stay!
Only one thing I wanted to have was, It'll be better if there were 2 sets of towels even for one night stay.... Other than that, I really enjoyed my stay!
