Very Close to JR Otsuka Staion. If you run, it takes less than a minute.
And only 1 subway stop away from Ikebukuro, we even walked to there.(took 2~30 mins).
Room it self is not that spacious, but for 3 is really enough to stay.
They have hair dryer, wash machine, clothe dryer, febrezes, towels, Shampoo, treatment, body wash and etc.
Ryo and Yuri helped us a lot via Air b&b chat, and they even let us do late check out on the last day.
And there is common area to keep our luggages after check out.
Will definately come back to this place again when i visit tokyo someday later.
