The flat is very nice. It is the area of Shin Okubo, a very busy area of Tokyo, film If restaurant and mainly attended by Japanese people (not many tourists) which allows you to better understand the city.
The flat is clean. The indication provided by the host helps in getting easliy to the flat.
The flat is ok for four people, even if the living room is a bit small.
The host is very far in answering and helping.
