The room and shared place was clean and really convenient. The place is close to the station and really close to Ikebukuro (one of the bigger areas of Tokyo, 3 minutes by train only).
The landlord was super fast in answering mails and was always friendly and helpful. Very good communication.
Other people who stayed in different airbnb rooms were sometimes noisy but that is not the landlords fault since wall in Japan are in general not so thick.
So I would really recommend this place for a shorter stay when your traveling or visiting Japan!
