Seiji’s apartment is a terrific location in Shinjuku! It was down the street from amazing places to eat, drink and game. It’s a modest apartment, with pretty much everything you could need for your stay . The WiFi hotspot he provided was helpful for us as well. If you’re sensitive to noise, you might want to carefully consider. Although it’s off of the main road, it can still get a little noisey at night. Seiji’s communication with us throughout our stay was notable as well. He checked in with us over email a few times. Overall, recommend for those seeking a modest accommodation in a great location.
