There was no room cleaning on Sunday - we were only told at time of check-in.
Early check-in (ie. before 3pm) needs to pay 2000 yen - we were only told at time of check-in.
You even cannot just leave your luggage at the concierge (for free) even though you arrived early - each piece of luggage cost 500 yen.
Guests can smoke in the hotel lobby - making the lobby very stuffy.
Sunday breakfast was buffet type - very good quality and reasonable number of choices. Mon/Tue only have set breakfast. If you are not too use to traditional Japanese type of of food, you might not find it too attractive.
The good thing is there is limited serving of rice (breakfast and dinner).
