"Excellent location just a block behind the train/bus station. Free buffet breakfast that was actually good and varied each day. Free drinks throughout the rest of the day, including filtered water and hot drink machine. Downstairs common area is relaxing and well maintained.
Room was large for Japan. You could comfortably open suitcases and still have room to walk around. Beds are also larger than other hotels. We booked 2 twin beds and they were also similar to a double size. Pillows are very flat though. "
