Good value Airbnb; 5 minutes from Nakano-Fujimicho Station with a 7-11, a supermarket, Daiso & restaurants nearby.
Sam is a very thorough host. He walked us to the Airbnb and explained how to use the TV, WiFi, etc.
The room on the lower floor is quite odd because to get to the bedroom, you must enter through the bathroom. Upper floor room is nice and cozy with a sofa couch & futon.
We did have WiFi issues during our stay & Sam tried his best to resolve these issues - unfortunately we were left without connection for majority of our stay (after all, we are millennials haha).
