Room was exactly as pictured and described. It's in a fantastic location very close to a very useful train station (Higashi-Shinjuku), though if you're planning to utilize a JR Pass it's worth noting that the closest JR station (Shin-Okubo) is a bit of a walk.
That said, I was given a room on the "first" floor, which is really a dug-out basement, and the air in the room had an awful dank smell, and it was legitimately difficult to breathe. I eventually checked out early as my sinuses would immediately flare up every time I returned. I'm assuming bad air had settled down into the room, and they really should not be renting that room without an air purifier or something.
Anyway, other rooms are probably fine, and it's a nice place aside from the bathroom being really tiny.
