Ayaka and her family made me feel really welcome in their house straight away! Even though Ayaka speaks little English we managed to communicate well and promptly. Since they did not have a previous guest on my check in day she let me leave my luggage in the room, which saved me a lot of trouble!
I found the house with little difficulty by following the directions she sent me (the address given by google maps was a bit off): having the university as point of reference makes it hard to miss and there is a metro stop not far away.
The house is beautiful and the room is spacious and on the top floor, giving a nice view and privacy.
Definetly reccommend this host for anyone wanting a good space in Tokyo, much better than a hostel and cheaper than a hotel!
