Koichi is the man, he had constant communication with me as soon as we landed at the airport so he can figure out when we will arrive at Shinjuku station where his airbnb is near. (about a 12 min walk) Location is decent as you can get to the main tourist area in about 10-15min walk depending where you are trying to go. Tons of shopping mall around the Shinjuku station, and Kabuki-Cho is also about 10-15min walk. the Room in a local residential area Koichi has bunkbeds for 4 and also you can set up 1 person mattress on the floor if bunkbeds isnt your thing. Overall I enjoy Koichi's interaction with us and his recommendation for food and his place comes with a pocket wifi which is super useful for us.
