Mitsuko is one of the most positive spirits you'll ever come across, she was very prompt with her responses and she tried to help us with any requests we made. Her house is located on a quiet one way street, but if you walk down 3 minutes and cross the street you'll find everything you need from restaurants, liquor store and many shops. Walk a further 5 minutes and you come to Hatagaya station which is 2 stops away from Shinjuku station which pretty much brings you to any place your heart desires. I recommend staying here with your family.
