Hayashi’s apartment was wonderful! While it was a bit of a walk away from the Nakano station, it was modern and had everything I needed for a comfortable one week stay.
The nearest convenience store is a Ministop other side of the street, and there is a lot of stores close to the Nakano station.
At times you could hear neighbors coming back home odd times which could wake you up, but sleeping with earplugs fixed that problem.
