A very convenient location right near the Oedo Line Ryogoku Station and about 10 minutes walk from the JR Ryogoku Station, with many convenience stores and restaurants nearby. We arrived after midnight but the area still felt very safe and we managed to find the place okay. Yoshi was very quick at responding to questions, had left clear instructions in the manual and had given us many amenities. The pocket wifi was incredibly useful, and we had a fantastic time in Tokyo thanks to our host!
