Pretty spacious location for Japan. I liked the tatami floor and I actually also liked sleeping on the floor with the Japanese futon. So if you wanted even more space, then you could fold the futon out of the way during the day.
The room is on the first floor, so you can hear the footsteps of the upstair neighbors, but they weren't throwing parties or anything like that.
The walk to the station to Shin-Okubo is cool since you'll pass many nice Korean restaurants.
