I'd say Lisbon, Portugal is probably the closest (including Weather, which places like Seattle are lacking), especially because you didn't mention pre-existing tech industry which is probably SF's main differential versus everywhere else. It even has a big red bridge?

P.S: I'm sorry Lisboetas..you are already getting swamped by Digi Nomads, but it's true.

I visited lisbon last year and was kind of shocked how similar to SF it was, weather, hills, general feel - that it has its own golden gate bridge really just sealed it.
