It's a great spot / location for a great price. I stand six foot, four inches and couldn't fit entirely in the capsule and had to tuck my knees a bit but it wasn't such an issue that it ruined my experience. If you really need the extra two inches to stretch out, you can keep your capsule door/mat open while you sleep (which I ended up doing). Most places in Japan are similar if you are tall.
+They provide a locker at no additional cost.
+The check out is super easy and convenient.
+The check in process is also very easy. (This is a huge bonus if you are tired and just wanting to get in and relax.
+The location is quiet and not far off from a near by train station. Maybe an 8 minute walk.
