Location wise : Well located near JR Okachimachi Station (But nearer to Shin Okachimachi). Definitely will need to be prepared to walk 5-10 minutes depending on which station you want to go to. Will only feel the distance on check-in check-out if you have big luggages to drag. But that's pretty much most airbnbs in Japan. I've been walking even to Akihabara and there's just so much to see along the way.
Listing : If you're confused about the room structure from the pictures, why it looks like 2 listings, it's because it really is 2 studios combined into one! Essentially you get 3 beds in two separate sections (it's connected in the middle). So ideal for families or 2 couples as well. (Note : Only 1 bathroom)
Other things to note : No lift. So you will need to carry the luggages up the stairs. (Again, not an issue).
Listing quality was great, very happy with the stay. Comfortable and good value.
