1: location is very nice, nearest station is next to Ikebukuro, which is one of the biggest and transfer station in Tokyo. And the house is located very near to Kaname-cho station. You have grocery stores, convenience stores, and drug store.
2: Response from the owner is nice and quick.
3: I stayed with my family ( including 2-year-old and 10-month-old son), and I think this house is quite good for family stay. you can use whole entire house and no need to worry about the noises.
4: Unfortunately, pre-cleaning is not good.
