Mitsuko's place is great! Super neat, in a great location. A couple of stations away from Shinjuko -and only 20 minutes by walk if you feel like you want to. Plenty of convenience stores a couple of minutes away, 24Hs open places. Bars, restaurant for al budget literally around the corner. A true experience of Tokyo. The host was extremely helpful . I strongly recommend Mitsuko's apartment for your next trip to Tokyo!
