Ohkubo was such a pleasure to deal with- always responding promptly to my messages and ensuring the check in process was smooth and easy. His access guide is very accurate. The location is a 4 minute walk away from a station where you can take the Yamanote line (perhaps avoid over peak hours or Saturday afternoons/evenings- complete chaos!) and a 10 minute walk and you're in the heart of Shinjuku. When you step out of the apartment you're surrounded by restaurants and shops. Bed was very comfortable and the apartment has a lot cupboard space compared to other apartments we stayed at whilst in Japan. Thanks for everything Ohkubo:)
