This is the apartment belonging to Tomoe Klarissa
The apartment is as follows;

Living Room
Kitchen
Tomoe's Bedroom
Bathroom

There is a step when you enter, to point out where you take your shoes at.

In the living room, there is a television across from the chair, another couch to the left of the chair, and an arm chair to the right of the chair.

There is a hallway a little ways behind the arm chair that leads to the bathroom, Tomoe's room, and Tomoe's spare room. There is another step up as you enter the hallway.

The kitchen is in a box shaped room that is connected to the living room by bother their corners.

And there is one room in the back which Tomoe has no use for.

Here's an idea of the layout x
