Acceptable Exam Environment

I have read what-are-the-testing-environment-requirements-to-take-the-exam but I'm not entirely sure what is acceptable.

Currently I have 2 options when it comes to taking the exam, from home or from a meeting room in the office. The testing environment requirements FAQ say candidates will be asked to remove non-décor items. I live in a small apartment without a spare room/home office, behind the desk I use for working from home, in a corner of the apartment, is a big shelving unit that cannot be moved and a coat rack hanging on the wall. On the shelving unit is everything from books to board games to bottles of wine. Will I need to empty the entire shelving unit and remove all coats before taking the exam? Can the selves be covered with a curtain or bed sheet?

The meeting rooms in the office all have windows and there will be people in the office, not the meeting room when taking the exam. Is this an acceptable location to do the exam?

Is a laptop webcam acceptable also?
