Stayed here for 3 nights. Hotel gave me a room on high floor with an amazing view of the city. Room was clean and comfortable but very small even though I've booked a semi double room B. I had some problems with my 2 26 inch luggage. So if you have more than 2 larger than a 26 inch luggage, do not chose this room size.
For ladies, note that the hotel do not provide shower cap. Collect your bath cloth, cotton pads/buds, tea/coffee/sugar/creamer at the lobby.
No 2nd pillows provided in room.
I regretted buying their breakfast plan. Breakfast voucher is only used at the ground level lobby at a cafe across the train concourse from the hotel. It's a toast or waffle set with tea/coffee. If you are staying more than 2 days, I suggest having your breakfast at a boulangerie next to this cafe which opens at 7am or other cafes on the other levels which usually open at around 10 am.
The best part of this hotel is it is convenient, right inside the train station. If you are exiting from a Shinkansen or Express train station, turn left after the fare-gate, walk a few meters and you'll see the hotel sliding door on the right corner.
