At first we have a hard time seeing his place, but thanks to their friendly neighbors, they help us find the exact place. We take the Uguisudani station and around 20mins walk to his place. Neighbors know it as Seido Hall or kendo school. Locating in Google Maps will be a help.
Mr. Hisao is very very nice and kind, he toured us to his home and our room. And become comfortable. The room is spacious, clean, and quiet. In the morning, there is a delicious sandwich and chocolates (oishi!) for us. More than that, when we leave, he offered to drive us to Nippori station. Overall, it is convenient. I will recommend your place to my friends too. Thank you!
