My family of four stayed in a north-facing room with a great view of the train tracks below. Somehow, seeing the trains coming and going was surprisingly mesmerizing. Of course, the view of the cityscape at night was terrific as well.
The room is fairly spacious in Tokyo's standard. The hotel is a bit dated, but you really can't beat the location. It took us less 5 mins to go from the hotel to the Shinkansen gate at Tokyo station.
