I really enjoyed staying at Alice's home in Shin-Okubo. It's very close to two supermarkets, some restaurants, a Family Mart, and in walking distance to a subway station (or 10 min from the JR). Home is large and I loved that we had two large beds, a rarity in large urban centers in Japan. Beds were comfy and peaceful at night. There is an elevator inside the apartment complex so bags can be transported with ease.
Alice was super communicative and responded to my questions, requests, etc. in a timely and friendly manner. Thank you for the warm stay!
