R Inn is conveniently located next to Araiyakushimae train station which is on the Seibu-Shinjuku Line. The area has lots of restaurants and a supermarket. Nakano Broadway is a leisurely 15-20 minute walk. Check in was super easy and done through a number touch pad. R was very responsive and even checked in halfway into my trip to make sure I had everything I needed. There is a small kitchen area in the apartment with cooking utensils. There is also a combo washer/dryer for doing laundry. If you're looking for a private apartment close to Shinjuku you can't beat R Inn!
