Please consider to walk about 10-15mins from home to Sakura-shimmachi station (non JR station) to go to Shibuya. The locations surrounded by many shops; family mart, foods (kfc, starbucks, sukiya, coco curry) no need to worry about craving in the night!
The place is not that big but still comfortable for two people. He gave us new towels every 3days.
Overall, Seiji’s house is recommended if you look for closest place to stay nearby the shopping center and worth the money as well.
