Spain trip with unusual work schedule - which cities? Thanks

22 day trip in November.

BUT, important: I work 4 days per week remotely (11 hours per day). And, i'm off work the other 3 days per week.

What cities should I go to?

I'm thinking Valencia. But where else? Maybe 2 more?

Other factors: I am a foodie. I need good internet (for work). I will be awake at odd hours (because my work schedule will be GMT-5, not local time.)

Thanks!!!
