It varies, working from home can be a horrible isolating trap and simultaneously much more productive and appealing.

Especially in the winter months, if your work day is now at your home with no intrinsic reason to go anywhere else, you wake up in darkness and first leave the house in darkness, meanwhile the agency you'd otherwise have is impeded by people watching your Slack status wondering where you are, it's not exactly ideal. With no physical difference between work and home, you and up basically always being at home, which can be dreadful at times.
