CJT House is a superb 3 storey house that is located within walking distance of Ikebukuro. Very clean, with plenty of towels and bedsheets for us to use. Instructions on how to use appliances were translated into English to make operation a breeze. I would highly recommend this place to any one with a large group (we had 5 and it was easily enough).
Family Mart just across the road which was really helpful!
Notes: Pocket Wifi does get quite slow at times, and any train stations are about a 10 minute walk away.
