You get what you paid for. It's a dorm style so you'll be surrounded by a variety of neighbors. Some who smile and start conversation others who don't. The amenities were pretty nice with the shower which was better than I expected. The wifi was wonky in my actual bunk so I usually had to go into the common area to get access.
The location is great and very convenient to get around Tokyo. You have immediate access to the seibu-shinjuku and Oedi lines. Which can take you any and everywhere.
I mean in comparison to a capsule hotel where you get a tv in your little cubby I still think this was a nice place to stay at for 13 days.
