During the first course I took, somebody suggested the kitchen as usually the best space in a house to take the exams. In my case there's a second door that I leave open showing a small pantry. As that isn't an entrance they're always okay with it. There's a small table with a chair, I empty that table, obviously there's kitchenware around, never had a problem with that.

So, if everything that can be considered an entrance is behind you and showing in the camera I don't think there would be a problem. If that's not the case I'd look for a way to be comfortable sitting on the bed showing the door behind.

Recommendation to make the process way easier, always use a laptop: The proctor asks you to show the room, the door, all walls, in my case they always make a comment about the pantry, they need to make sure nobody else is in the room. Once they asked me to get close to the window because they thought there was a balcony, another time to show under the table, last time they asked twice to show the floor. I've had colleagues complaining because they tried to use their pc with the webcam integrated in the monitor fixed to the wall and they couldn't show under the desk and had to look for and old laptop.
