Very convenient place, right next to Ikebukuro station. Super clean, you'll get one towel/night you'll stay. It's a capsule kind of hostel but I really appreciated the privacy space you have next to your bed (with a locker, a small table, a chair and a couple hangers). 1F is for men and 2F for women, there are security cameras on each floor. Toilets and bathrooms are common (again separated 1F men 2F women) but very clean too. The only thing you should be aware of is that you can hear the trains pretty much.
