Keiko is very kind to welcome us at the Minova subway station close to her apartment. She brought the umbrella to us in the rainy day when we arrived and was very helpful to lead us to her apartment. Keiko's apartment is spacious and wide, with the full equipment for the cooking. We chose to sleep comfortable on the traditional Japanese Tatami floor, enjoying the coffee produced from the coffee machine in the mornings, taking the subway convenient and efficient to access the major sightseeing locations. The traditional civic market (with an old railway channel crossed) nearby is worthy for the wandering and discovery. Keiko and her son welcomed us to taste a very delicious but affordable steak dinner at a local Japanese restaurant, brought us to enjoy the night views of Tokyo. Keiko is a very kind and friendly host with the open-mind.
