It was very difficult to fit 7 adults in this space. We had three couples and a single adult, and it was hard to relax in this space, where no room had a door, so no one had any privacy. There was very limited seating, the beds were rock hard, and the two couches were extremely firm as well. The folks who used futon on tatami slept better than everyone else. Also, this place is right next to the train tracks, so the train was looooud. Whenever one came by (which was like every couple minutes between 5am and 11pm) you had to just stop talking and wait for it to pass.
That being said, the location was *fantastic*. The train station was super easy to get to and via the Yamanote line, pretty much anything you wanted to get to in Tokyo was right at your fingertips.
Yuga was super responsive and extremely helpful to my entire party. All in all, it was a decent stay, and if he changed the mattresses and couches I would definitely stay again, but only with a much smaller party.
