I found this place easily thanks to the google maps gps coordinates provided. It is quite a walk from the nearest station (Asakusabashi) but still ok. When I got there, the staff was confused and didn't know which room was mine. They had to make a phone call.
When I entered the room, the window was wide open with nothing block insects from coming in. The place was not extremely dirty, but cleaning the walls and the floor once in a while might not hurt. The men's bathroom smelled of smoke.
The walls are paper thin. 2 girls woke me up the first night at 5:30 am by only talking.
I did enjoy the privacy of a room, but hostels are much more worth the money.
I recommend this place if you truly want the limited privacy of a room with non-soundproof walls. Otherwise, look for hostels.
