Yukio was an amazing host. He picked us up from Tsurukawa station when we arrived and even drove us the extra distance to Machida station when we left. His place is neat and tidy and feels like a real Japanese house. Stairs were a bit steep though but you get use to it. Shinjuku was a bit far away, but if you time the bus and trains properly and take the Express trains, you can get there in less than 50 min. Machida is a big city and there is lots of shopping and amenities near the station and around such that you do not even need to go into Shibuya or Shinjuku. This is the place to stay if you want an authentic local Japanese (non-touristy) experience. We'd definitely enjoyed our time there.
