I can recommend you staying at Aileen and Naoki apartment. The location Nakano is perfect as a hub to travel around Tokyo, catching Chuo line and than at Shinjuku catch the JR Yamanote line. Also Nakano is a spot definitely worth to check around. The apartment is perfect, it is as described in the picture and clean. It has all what you need (microwave, cooker). Love the shower system with a fan, cool, dry functions. Also around the apartment you have lots of stores, supermarkets and restaurants. Check-in is easy and clear instructed by Aileen and Naoki. Communcation was also good. Thank you so much Aileen and Naoki for staying at your place. We have survived also the Typhoon Hagibis ありがとうございます
