Shizuka's place is indeed a Japanese experience, and that comes with the good and different. The apartment is very Japanese, from the bathroom in which you can shower inside or outside the tub, to the non-existent insulation. The heater took care of the cold on the Tokyo winter nights. This is not to criticize the apartment, it is indeed normal for Japan to have no insulation. So one side of the bed can feel like an oven, the other side like the north pole. Overall it is a great experience, but a small space in which two people can fit in. Again, think Japan.
The neighborhood is great, a small walk to the metro station, but you have a 7-Eleven next door and many small restaurants nearby. The access and communication were flawless, and I would like to return there if I had the chance. A great gateway into discovering Tokyo and very immersive experience into Japanese living.
