We loved staying in Manami's place. The apartment was very clean, quiet, and well equipped. Manami very kindly helped us with whatever we needed. The location was also very ideal. There's a well-stocked store right around the corner which made grocery shopping very convenient. It was also very easy to get to popular places like Shinjuku/Shibuya/Harajuku from Koenji station and there are some large main streets with tons of restaurants and shops within walking distance. I very highly recommend staying in Manami's apartment if you're coming to Tokyo!
