Ohkubo was a very pleasant host to deal with! We booked his place on the day as we had a slight change of plans and Ohkubo could not have been any more helpful. He provides very clear instructions on how to find the apartment and how to do the self check-in. His communication was fast, the place was very nice and clean and he even provided some souvenirs and snacks for us especially. The pocket wifi he provides is also a very good one, fast and has great connection. The location is very close to JR line so accessible to most place and also is a 10 min walk from Shinjuku! Thank you, I would highly recommend this place.
