Koichi’s place is a very clean and is accessible to many areas like the shopping district, train stations and such. There is a convenience store near the place so you won’t need to walk far when you need to buy something. The area is quiet so you will have a good night’s sleep. Koichi is also easy to contact and he makes sure you are okay during your stay in Japan. 10/10 would stay at his place again if we come back to Tokyo!
