Hiroyuki is a nice guy and very friendly. He gave me detailed map n instruction about how to get the key, how to walk from nippori station and Sendagi station which is clear and easy with reading with many pics step by step. His house is decorated very beautiful and traditional Japan style,I like it when I first see it. ONsen is traditional Japan public bathroom which is a bit hot for me. But it is so nice to enjoy it after long day walk. Guest could use it for free and without time limit. You could hear the sound of water in ONsen which is a bit noisy in the night. But I was too tired to care about this. Overall it is very nice place to live in Tokyo. Sendagi station is 1 mins away and nippori is about 10mins walking. Ueno park is 15mins, it feels good to go through residential area to there. I will recommend my friend to live. Only thing which is hard for me to separate rubbish. I am so sorry to leave that to Hiroyuki, just separate bottles and others.
