Akemi's place is conveniently located not too far from Square Enix's headquarters, subway lines, a 7/11, and even a JR station, but far enough away that the space remains nicely quiet and calm.
Had a great time staying in the space for a few days - Akemi is also very responsive and caring, and has an incredibly detailed guideline to help newcomers out with the check in, amenities, and space in general. (Self check-in).
Would certainly stay again to explore Shinjuku/Tokyo!
