Wonderful response time! Spontaneously decided to make a trip down to Japan with my sibling. Did not get a chance to book an Airbnb until we were already on the train making our way to Ueno station. A half hour before arrival to Ueno, we booked, roughly 15 minutes later we received a reply and Shigenori accepted our request.
Fantastic place to stay, convenience store across the street, ~500m walk to the market, and 25 min walk to the Akihabara.
Also, if your Muslim, there is a Mosque down the street about 100m and halal ramen restaurant couple doors down.
