"We happened to choose the Japanese style room for our family of four - it was amazing! one tatami room with the four futons, and another slightly smaller with a low table to sit around. A long hallway ran along the two rooms with the sink and plenty of space to store toiletries and change, and then the shower/Japanese bath at the end of the hall.
Coffee and tea supplies were there in the room, along with typical Japanese amenities like yukata and slippers.
We also signed up for the breakfast buffet each day, and it also was wonderful, with a wide selection of Japanese and western food items. Waffles and omelettes (by special order) were included. The staff in the eating area and the front desk staff were very courteous and helpful.
The hotel also had a small laundry room with two small washers and dryers which we used.
The hotel location is pretty decent. It's about a ten minute walk from Niigata station, maybe fifteen walking with suitcases.
After this experience, this will definitely be the place we stay in Niigata in the future - and I recommend the Japanese style room over the Western style rooms."
