Perfect place to stay in Shinjuku. Very nice neighborhood. Restaurant literally right downstairs and convenient stores less than 5min walk. JR line station near by, about 10min walk if you are using the JR rail pass. Local subway is 5min away. Pocket Wi-Fi was a bonus, especially if you plan to explore.
Host was very helpful with instructions on how to get to the location. Easy self check in and comfortable place to stay. I will definitely stay here again if I stay in Shinjuku.
