Kumiko and Koichi are 2 great hosts. They really make your arrive in Tokyo easy and smooth (thanks again for the biscuits and the orange juice ;-) ) The apartment is in a awesome part of Shinjuku, it is a quite neighborhood, but it is near to the center of Shinjuku. The room is quite big. Iwould really suggest anyone who want to spend some day in Shinjuku to stay in this apartment.
