The location is great. I did get a little confused on how to get there but eventually found my way. It's very close to ame-yoko, ueno station, also close to tokyo metro okachimachi station (naka okachimachi and ueno okachimachi). If you plan on staying here, fyi, the place is reaaaally small, so if you plan on brining big luggage, good luck on finding space on where to place it in the room. Also, there's no conditioner in the bathroom so bring one.
I think the cost is a bit pricey, I've been on other airbnb in Japan and the rooms were bigger for similiar price point, but you're paying for the location.
