Good: staff was friendly and helpful, location is close to most everything in Shinjuku.
Bad: first and most important, the ac either wasn’t on, or was so inefficient it seemed that way, it was cold outside, but when you walk in, you’re immediately sweating, immediately bummed me and my friend out. I also woke up drenched in sweat at 1 am so that was fun. Next, it’s claustrophobic and smells bad probably because of that, you walk in to the smell of musty feet, and the locker areas are super cramped. Speaking of lockers, they’re not spacious at all, barely enough room for a bag and the towels they give you(which also are bad…). Funnily enough, my locker actually broke when I opened it, so that made me feel secure with my items. Check out process was similar to other capsule hotels, you just HAD to check out, which made it a little annoying because then everyone was crowed on check in and check out, which made it smell worse. Bath was okay, just the foundation of the room wasn’t well maintained so it was kinda sketchy.
All in all, absolutely not staying here again, not worth the discomfort.
