This is a small, clean and nice, basic apartment, which is perfect for two person. For us the train was not diturbing at all. Actually, I can remember only one or two times when I heard it. The closest station is for 1 minute walk, Shibuya is for 30 mins by metro with one transfer. There are restaurants and grocery stores very close to the building. Our host was kind, helpful and he replied back very quickly. This user guide for the air conditioner can be useful. https://www.linguajunkie.com/japanese/japanese-control-aircon?fbclid=IwAR1kSziiywslF0z14bzF6iv2KFHffWOW0H3Yw-qKTxW5AL70um2c8zDVkP0
