My friends and I had the best time staying at Koichi's apartment in Shinjuku. We found it super convenient as it was only a 5 minute walk from the atmospheric Golden Gai, with its eccentric bars and bohemian characters. The apartment is super clean and we enjoyed eating the snacks Koichi generously left for us. We enjoyed meeting Koichi during our stay in his flat and we found him very accessible throughout our stay. On our last day in Shinjuku Koichi showed his incredible hospitality by very generously helped us out with transport when we in need. Much appreciated, thank you Koichi!
