was a great host and a great location, was close to the train but we weren't disturbed by any noise. On one side of the apartment we had the shin-okubo station with the yamanote line for most places and on the other the local chuo line (yellow) for places such as Nakano and suidobashi(Tokyo dome, an amusement park and so on). The host replied really fast and was really helpful. Was a really nice stay and I would definitely recommend this place, host going above and beyond to help. Walking distance to Shinjuku, took 10 min tops and was rly easy to walk after the first walk (used google maps). Out left, first right and walk a few m, after that you see the okubo south entrance to your left :) to the right for shin-okubo :)
