We stayed on the premium suite on the 5th floor (there's another one on 2nd floor).
Room was huge, especially when comparing to japanese standard of very small hotel rooms.
The hotel is maintained properly but you could see that it is very old.
The room had a safe but I wouldn't count on it as it isn't connected to anything, so someone could just pick it up from the room and steal the entire safe..
Dinner + breakfast was so so, but Its probably because we're not fans of this kind of food, but it was an interesting experience. Only bad thing about dinner was that it looked like the restaurant staff tried to rush us to eat quickly, as they've waited no more than 2-3 minutes before serving each dish (there were about 7-8 dishes), so by the time we barely tasted something, the next dish was already served..
