Great modern place. Stayed with my wife and it was perfect for us. The place had everything we needed.
Washer dryer was useful. If the clothes still a bit moist, bathroom fan has clothes drying mode to quickly dry clothes. There is wardrobe that is big enough to do ironing.
Kitchen is small but had everything we needed. Umbrella and vacuum cleaner was handy during our rainy stay. Pocket WiFi is much appreciated while exploring Tokyo.
The area has many restaurants around Nakano station. There is Nakano walkway which has lots of shops.
Will stay again, if we're back.
