Kevin was a great host, always very quick to respond and so helpful and friendly! We had a great stay at his place. Though the closest station to his place is on the subway line (i.e. NOT the main JR train lines), it really is a 1 minute ride to Shinjuku and as long as you factor this into your travel time, it's fine. There is a 7Eleven (with what we believe to be some of the friendliest staff in Japan!) and even a 24 hour restaurant within walking distance. The place is clean, comfortable, and well-equipped. We would happily recommend Kevin's places to anyone visiting Tokyo :)
