Lake towns and hill towns? Varenna and Spello, or Todi, or if the hills are too much, Bevagna - the hill town without the hill. All in Umbria.
Or a bigger town like Lucca in Tuscany?
Have you been to Puglia? Or Matera in Basilicata?
With Bellagio, that pairing would be cool/hot, wet/dry, rich/poor.
