Very nice place, great location and value. I've stayed for 6 nights, and most of time it was really quiet, yet it depends on other guests.
Somehow I was expecting the capsule itself to be more secure, while it just closed with a light curtain, so everything valuable should either be stored in safe inside of the capsule or in locker outside.
Also, the spare items like towels or charged adapters are present but they are not easy to find if you are not looking for them on purpose.
