Likewise, there are a lot of nice cities in Belgium that offer various balances of those requirements. I settled on Ghent, but Brussels has more nightlife and local forests at the cost of being dirtier and somewhat uglier. You might also like Liege, which is close to some excellent hiking and thermal baths.

I've been seriously considering Taiwan! Sadly the current instability in its relationship with PRC makes me fear going there if war breaks out.
