My own experience working from home probably follows this. I've gone back to work now, but I spent 6 months working at home. At the end it took me 12 hours of time to make up an 8 hour work day. It was just not sustainable for me.
Granted they are privileged enough to have their own home office, with a door and are able to play music without headphones, and have no kids. As opposed to the office, which is in a cube farm.
I live alone and practically next to my office, so while there's still advantages it mainly means I have to do chores more often and cook a lot more.
