Please note that this airbnb is 4 levels and no internal staircase to connect the floors. The stairs are on the outside and it can get slippery especially when rainy.
Cleanliness could use a lot of work but the host arranged for another cleaning later and helped to get a new kettle thankfully.
Location is really good though. Just 5mins from a station 2 stops from Shinjuku. Nearby park is great and restaurant variety too.
