My husband and I (in our 70's but pretty fit) are planning a week in southern Tuscany next September. I have read thousands of reviews, opinions and forums and still can't decide whether to base ourselves in Cortona or Pienza. Pros and cons of each place please! We will have a car and want to find a self-catering apartment in the center of the town. Happy to visit all the usual places during the day, just want to know the best town to return to and enjoy most of our evenings there. Thanks.
