First off Kevin is an amazing host and will help you out in any way needed, he is always willing to help out your group especially with his knowledge of the area and will give you great tips on where to go. The location of Kevin's house is a 5 minute train journey from Ikebukuro which is incredibly helpful for getting anywhere in Tokyo. The house was everything my group and I needed for our time in Japan. I would 100% stay here again when I visit Japan in the future and would recommend it to anyone.
