That sounds awesome, and might get me to switch from my current job.

But next year, I'll have 22 days off, which is pretty close, 2x in office (not strictly mandatory, just need to give notice if I WFH), and my boss is really flexible about remote work (we've had people work remotely for 1-2 months at a time). Not quite as nice as your gig, but in the same ballpark.
