Poor mgmt, won’t even let me leave luggage until checkin. (The latest checkin ever 5pm! And checkout 10am!) Poor hospitality. 3rd no elevator. Tiny tiny space, tiny bathroom - even the stupid ‘wardrobe’ look limits your already tiny space so you bang your head in it when getting in and out of bed. Bailed after one night - for the same price or less. take the generous Unplan at Shinjuku instead.
They host cooking classes on the only public space
There is only a little kitchen on the first floor as a public space. This kitchen is the only place where you can sit as the bedrooms are tiny.
The worse part of it is that hostel rent this kitchen to outsiders for cooking classes(!).
During my stay, there were two times when the kitchen wasn't available from 10 AM to 4 PM! At one time it was a stormy day. It was a radically uncomfortable experience
I would suggest staying instead in one of the capsule hotels which you can find also close to Roppongi.
