The Hotel is awesome, the room is really nice, just that is an extremely complicated Hotel, for the price you don't get the service, you get a nice room, but everything is annoying.
For breakfast, they dictate the schedule, and the occidental menu is always sold out, so you must have Japanese cuiisine at 8 am, with some might find nice... but still there should be the option for timing and preference between oriental o occidental food.
Also for dinner, this is a Hotel who tells you at what time you will have your dinner, you don't have to much of timing options, neither choices.
For spa don't even mention, impossible to book, you must book your spa session few weeks in advance.
Onsen is great, people are extremely nice, but just needs some customer friendly timing and service.
I dont know if I would recommend this place, for 600-700 usd per night, there are much nicer and more customer orientate places.
