Choose a cosy London capsule hotel in a shared dorm for a sociable vibe, meet like-minded travellers, and swap stories or book out an entire dorm for a private group adventure.
This is literally the opposite of what I would want. It would be great to see a privacy and rest focused concept for this, which is what I associate the Japanese ones with, a place for exhausted salarymen to get some quick rest, rather than a backpacking hostel. Nothing wrong with the latter if that’s your thing but it’s not going to appeal to anyone over 25.
In 2023 I stayed in a capsule hotel in Bilbao. There I was told at check in that no talking or loudspeakers of any kind is allow in the capsules. That can only be done in the lounge area.
I spent 3 nights and got much better sleep than I would have at a hostel.
