Akemi was responsive from day 1 and made the check in procedure clear and painless. The apartment is located a 5 minute walk from the station and you are a 15 minute walk or bike ride from anywhere in the Shinjuku district. the apartment is a little old, sure, but for the value you get, the privacy, and being in the heart of Tokyo I don't think you could actually find a better deal, at least when I was there.
I won't be returning to Tokyo for a long time, but I sincerely hope their place isn't booked when I want to come back.
