Had a Japanese futon twin for our 4 nights in Tokyo. The hostel around a 20 minute walk from main Tokyo station.
The rooms are small with little room for bags, and futons living up to the name of being hard, did take some getting used to.
But apart from those 2 critiscms we had a good stay. Felt clean and the communal floor was good for chilling or eating. Location wise a few minutes from central ginza with loads of places to eat and shop
