What does の do in 部屋の模様替え?

Here, の links two nouns:

• 部屋 = room
• 模様替え = rearrangement / redecoration

So 部屋の模様替え literally means the room's rearrangement, but in natural English it is more like rearranging the room or redecorating the room.

This の is not only for possession. It often means related to, for, or about.

What exactly does 模様替え mean?

模様替え usually means changing the look or arrangement of a space.

For a room, that often includes things like:

• moving furniture around
• changing the layout
• changing curtains or decorations
• giving the room a new feel

It does not usually imply major construction. It is more like rearranging or redecorating than renovating.
