Using a significant chunk of my own salary each month to pay for something I used to get for free (and that my employer should provide) hardly seems like the ideal solution.
In my experience, most decent employers have a stipend for co-working anyway.
I can easily get up at 6 go workout for 1-1.5h then drive to work when the morning rush is gone.
I'm saving at least $400/mo just on parking and gas right now.
Even if my employer wouldn't reimburse anything (never asked), I'd eat the $80/mo to save myself 2-3 hours a day commuting.
This is the case for a large proportion of people in the South East of the UK.
