Kei is a very good host. He has set up a good house rules that we have to comply, but don't worry there is no time restriction if we want to go back late at night, just make sure we don't make too much noise. The bedroom is large and can accommodate 3 people easily. It is japanese style with tatami and futon. The futon and the comforter is very comfy. There is also a living room with kitchen set and TV that we can use. Kei's place is 10 minutes walking distance (walking leisurely) to the Aoto station. From there we can explore Tokyo easily. Also from Aoto station there is an express train to the Narita terminal. A big plus :)
nb: for Indonesian airbnb'ers if you want to stay at Kei's place please bring some indonesian chilly sauce for him (abc, belibis, etc). He likes it very much :))
