Had an 18 hour layover in Tokyo, The Millennials was in a great location in Shibuya. Never experienced a capsule style of hotel before, although a little strange at first, there was a clean bed and clean amenities. The storage was adequate, but keep in mind that only a pull down shade is your “door” so keep your valuables in the lock box provided under the bed or just take them with you if you leave.
I missed out on the free beer happy hour! But there’s plenty of shopping, eating, and drinking establishments within walking distance. Also a short walking distance to Shibuya train station
