This apartment is a pretty good place to be staying in Nakano.
I really recommend this place for a convenient stay.
Its a very clean and modern living space. The kitchen has everything you need for easy cooking.
The room gets very bright and inviting during the day. The negative side of this is if you prefer to sleep in the dark, there is no way to darken the room for the morning hours. The curtains do not block the light from outside good enough.
Alot of supermarkets are between 1 to 5 minutes walking distance. Also the Nakano Broadway was easy to get to by foot.
I took easy walks to Kōenji (15 to 25 mins) and longer walks to Shinjuku (40 to 50 mins) explore the area. I enjoyed that alot during my stay.
I would come back to Nakano anytime as there is much to see and experience.
