If I could give Koichi 6 stars out of 5, I would. I'm usually fairly critical on small details but Koichi has far exceeded my expectations. He has kept in touch very promptly and quickly with the information that I have requested. Upon check in, he messaged me to inform me that Shinjuku was raining and that he would be willing to pick me and my party up at the station; things were already off to a good start. We got lost along the way due to exiting at the wrong gate and after some extended time getting our bearings, he messaged me worried of our whereabouts; more bonus points. Eventually we arrived and Koichi met us, gave us the tour and the tutorial of what to expect. The photos of what you see are exactly what is provided in the AirBNB, there is no photoshopping or enhancements. A/C and other amenities are top notch. During the course of our stay we needed to get some scissors. Although, I could not find any, Koichi had them in my hands within 10 minutes. Needless to say I was impressed with his rapid response. Another instance happened where the WiFi unit had failed, he had another one working in my hands within 10 minutes of messaging him. Lastly, he was kind enough to drive us to the station upon our departure, and I couldn't thank him enough. In summation, 6 out of 5 stars. Stay with him and he'll make your trip to Japan so much better. :)
