Min is a really nice n kind host! No just give u the key n leave, he also will tell u the info about the place n guide u for this areal. If u need any help u can ask him. I think he will love to help u!
The house clean n the location is nearly for the station or supermarket. Also u can walk like 5~10mins to Shinjuku. Its really convenient! In those day I live in Mins house, the people who I met are really friendly. So don't be shy or afraid If u want to try a different way of ur trip!
