Stayed here with 5 other friends and it was great for our needs. The sleeping situation and single bathroom was a little less comfortable for 6 (2 in each double bed, 1 on couch, 1 on floor mattress) but worked. Very clean and aesthetic place in a nice, peaceful location that’s only a 5 min walk to the closet subway station (~25min walk to the main Shinjuku train station) and has a 7/11 right around the corner. Also, check in/out is as easy as it gets.
