I chose this while traveling on business through Tokyo. I thought I could save a lot of money since all I needed was a bed to sleep in. I got the bed I paid for, which was decent. BUT, 1) Noises come through the flimsy screen that passes for the "door" to your capsule. I heard quite obnoxious snoring as well as the usual sounds of guests coming and going. 2) There is terrible ventilation in the capsule. A tiny little fan at the end pulls air in, but it was not enough to keep the air in the capsule moving and it got rather hot and stuffy. Plus the fan was incredibly loud for its small size. 3) This is right next to Shimbashi station, where trains run until 12:30 or so and then start again around 4:30 a.m. You can hear each train's arrival, the platform announcements, the jingles they play...all in all I got almost no sleep.
