Book Tea Bed Ginza - Hostel

As neither a heavy nor light sleeper, I found the sleep quality here better than usual for a youth hostel, even in a capsule located right next to the shower; comfortable foam mattress, decent soundproofing, and the blackout curtain worked well. The hostel is not a social space, but perfect for reading and resting, and the location was superb - the restaurants under the tracks near Shimbashi are a must-try.

The site doesn't specify, but the price difference between the three types of beds seems to reflect whether you're put in the more spacious area with the bookshelves, or the narrow corridor by the showers (and very far from the luggage storage area on the other end of the room). Only the pricier capsules have safety deposit boxes.
