This was our first Airbnb. Although we didn't met Kazu he was very friendly via message.
Being used to some hotels in Tokyo this room had a lot more space. And if needed there is was a little kitchen with tableware. The bathroom was clean and with amenities (soap and towels). The bed is a little hard for some people but I liked it.
The house is just a few minutes from nishi shinjuku go chome station and lets say 10 minutes walk from shinjuku station. I would recommend this place if you want to be close to Shinjuku/Shibuya/Ikebukero.
