This place is awesome. It's located west of Shinjuku (heart of Shinjuku) and you take the train at Shin-Nakano station to get to the main JR Shinjuku station and from there you can pretty much go anywhere in Tokyo. One night i was out and since the trains stop running around midnight i walked back to the airbnb (granted it was a 25 min walk but it's possible for me haha). The room upstairs are roomy and the heaters felt great. On the bottom living room is excellent. I'll say you can comfortably fit 4 people super well and 8 people will be fine as well you will just have to sleep on the first floor. It's sooooo worth and it was worth the money will gladly stay again. And it a quiet part of town and the 7eleven across the street was super convenient
