JoJo is very nice and she has probably response to all my questions.
The house is big, clean, very comfortable.
If you are taking train from the airport to Ikebukuro station with your luggage at the 1st day arrive, I suggest you better to take taxi from the station to the house (JoJo also provided the way to take taxi) as it's located in a residence area and you may take some time to find it. But after you settled, you may find it is not too far from the house to the commercial area
