The place was definitely a bit too cozy for 3 people, but still manageable- may be better for a solo or a couple. The location was pretty nice and quiet, as it was more of a residential area/ alley, and was away from all the hustle and bustle of the main Shinjuku area. The overall stay was not bad since we were only really there to sleep, and I wouldn't mind staying again if I come back to Japan!
