Most of all. The bnb acts as best basecamp for travling around central tokyo. You can access 1. Higashi nakano station (JR chuo/sobu, Toei ooedo line) , or 2. Ochiai station(Tokyo metro tozai line) by foot within 5 min, which makes you access downtowns and land marks of japan (Tokyo station, ginza, ikebukuro, akihabara, nakano, shinjuku etc) by minimum transfer and short time.
To be honest, the bnb is kind of old but everything is clean, tidy and functional. Nice place to stay comfortably like your house. I enjoyed the stay like i was in my old rented apartment in japan.
If you want to experience what is it like visiting near home restaurants/bar in japan. This is the place. From higashinakano station to your stay, there are all kind of restaurant on the road. From old style japanese cafe to kebab juction, ramen, yakiniku, dorayaki bakery, korean food, and japanese style-italian restaurant. There are also fine bar just around corner from your house (my visit was around december2022)
