Very, very nice hostel.
I'm 33, so keep that in mind when you read my old-man's review of the hostel.
I stayed in one o the 'capsules.' Hostel was clean and well organized. Showers were good, and bathroom was clean. Capsules had individual fans and light, which allowed folks to turn lights off relatively early (11pm) even if they wanted to be on awoke in their capsules for a little longer. Staff was nice and polite. Price is fair. Would certainly go back.
