Haruko is one of most nice and caring person I have ever met. She made me feel very at home for my first time in Tokyo. Definitely would stay here again. Her house is a about a 6-7 min walk from the Jiyugaoka Station. If you're looking for a cozy, home experience I'd definitely stay here. The environment was similar to a "living" with your housemate type of experience in a shared house. I'd only stay here if you're comfortable with that.
