The apartment was exactly as advertised. There is a kitchen and a living/sleeping room, 2 people can live here without any trouble. Everything is provided: kitchen equipment (rice cooker, microwave,..), a laundry machine and even two bikes are included. It's a 15 min walk to the train station, from there it's around 30 mins to Shinjuku (380 yen). A supermarket and many dining options are close to the apartment.
Ken is a nice host. He met me at tsurukawa station and his mother drove us to the apartment. He explained everything in detail and has much helpful written material for you. During my stay he asked if everything is alright. The best aurbnb experience so far! Thank you!
