This is my first experience to travel alone and live with host. Haruko-san is friendly and warm, just like my grandma. She prepared rich breakfast for me every morning. I love chatting with her during breakfast, though I just know a little bit of Japanese. She is not familiar with English, so if you can speak a little bit of Japanese, that would help. The tatami room is clean and tidy. Enough space for single person with a 27" luggage.
The location is good. There are supermarkets nearby which closed after 12am. Many small shops and restaurants near the train station. 5~10mins' walk from station to Haruko's house. Her place is in local residential area so it is very quiet and relax. I highly recommend Haruko's home if you are looking for a relax trip and a great homestay experience!
