I love the concept of the capsule being part library and cafe. The staff cool and professional. I stayed for three nights and it was okay. Quiet and restful, however I need to mention the weak WiFi and how stuffy it gets in your “cubby hole”. The common area is hip and allows you to chill. Overall it was okay.
Great hostel for the busy young traveller in Osaka. Nice and helpful staff. Good cafe. Good variety of books to read.
Cons: The bed pods don't have very good ventilation. I think the hostel would greatly benefit from renting out small plug in fans for visitors that need it.
