This is not a nice hotel. Since the Expo is in Osaka, I had little choice. The trains are very close (so close you can hear them until after midnight). You also hear the road noise which is very loud. The bed was small and lop-sided. The bedding was inadequate. The bathroom was disgusting, it is all plastic and does not vent well, meaning it is very gross after just one shower. They also refuse to clean your room more than once during the stay (I was there four nights), and you also have to tell them by 10AM if you want the room made up. Totally inadequate. They also have this absurd policy where you cannot have guests in your rooms. I paid for the room, I will have whoever I damn well please up there thank you very much. Had their advertisement listed this intrusive, backwater, and entirely unacceptable policy, I would not have stayed here. I wish I had spend two to three times as much to stay somewhere decent
