We total stayed for 5 nights at Seiji's place. He was very thoughtful host and the place was amazing. Close to train station, walking distance to Shinjuku station which was great for us as we had to catch the express bus to Mt Fuji. It was very conveniently surrounded by 100yen shop and lots of food choices. The house was nice and clean, very spacious for 2 of us and we got to experience living in a modern Japanese style home. I will recommend to anyone!
