What is the setting of the main scene?

From the text:

The scene remains the same throughout the play. It is the top floor of a warehouse and office building in Amsterdam, Holland. The sharply peaked roof of the building is outlined against a sea of other rooftops stretching away into the distance. Nearby is the belfry of a church tower, the Westertoren, whose carillon rings out the hours. Occasionally faint sounds float up from below: the voices of children playing in the street, the tramp of marching feet, a boat whistle from the canal. ! The three rooms of the top floor and a small attic space above are exposed to our view. The largest of the rooms is in the center, with two small rooms, slightly raised, on either side. On the right is a bathroom, out of sight. A narrow, steep flight of stairs at the back leads up to the attic. The rooms are sparsely furnished, with a few chairs, cots, a table or two. The windows are painted over or covered with makeshift blackout curtains. In the main room there is a sink, a gas ring for cooking, and a wood-burning stove for warmth. ! The room on the left is hardly more than a closet. There is a skylight in the sloping ceiling. Directly under this room is a small, steep stairwell, with steps leading down to a door. This is the only entrance from the building below. When the door is opened, we see that it has been concealed on the outer side by a bookcase attached to it. ! The curtain rises on an empty stage. It is late afternoon, November 1945.
