My mother and I stayed in Aiko San’s place for one night while transiting through Tokyo on our way back to our home countries. The location is very convenient as it sits on the Yamanote line, which is one of the better transportation options to go around Tokyo. We got from Tokyo station in the train in 10 minutes. The space was bigger than expected as there were two separate rooms. It could house 3 people comfortably. It also has a small kitchen area. However, like many Japanese accommodation, the bathroom was very small for a 2 meter tall person like me. We would highly recommend! Thank you!
