Ohkubo's humble apartment is one of the best places I've stayed through Airbnb. It's super convenient to local stores, food shops, and a JR line station (Shin-okubo). Quick 10-15 min walk to central Shinjuku shopping area too. The space has all the necessities you need, plus it's clean and tidy. Ohkubo is a great host, very friendly and generous. He answers pretty much right away. I'd definitely recommend my friends or family to stay here if they ever want a place in heart of Tokyo.
