I stayed in 3 Airbnbs and 2 hotels during my 2 week stay in Japan. This place was the second cleanest and comfortable (aside from my last $$$ hotel stay). Highly recommended and would stay again. About a 7-9 minute walk from your choice of JR Ryogoku station or Morishita station. Comes with pocket wifi and has an in room washer.
Cons: Walls are thin so you might be able to hear the neighbors.
