Great place!
There are three sleeping rooms; two with two beds each and one with two sets of bunk beds. The dining/living space was nice for hanging out in, and everything matched the listing and worked as expected. Clean and comfortable.
The location is relatively close to Ikebukuro station and not too difficult to find. Very convenient.
The area is a little seedy at night, but still feels fairly safe.
Having only one key for 7 people was a bit difficult for logistics, but I understand that that's pretty normal.
Overall, I would recommend it and would stay here again.
