A small room, but adequate for a short stay in Naha. There was an odd smell when entering the room, but it was easy to ignore. Bathroom + shower were OK. I found the desk a bit cluttered - I think the microwave oven was unnecessary (a safe would have been more useful).
There are some convenience stores in the area, and it is quite easy to get to from Miebashi monorail station, about 8-10 mins' walk. If arriving at night, be aware that some of the route between the station and hotel is not well-lit, but overall I felt quite safe after dark.
