Koji & Nami were fantastic hosts. I stayed for 5 nights and loved it. The accommodation is pretty much your own separate apartment, it has a kitchen, bedroom and toilet. it was much nicer than any hotel or hostel I stayed in during my month in Japan. Very close to the train station and with a few transfers you can get anywhere. I felt so at home during my stay and got to hang out with Koji, Nami and their friends. They were so helpful with directions and offering advice on sights and places to eat and drink. Got to see 'deep Japan' as they put it. It was so much fun they are super cool, super friendly people! If you get a chance to stay with them - definitely take it. Super cheap as well for how great it is!
