My husband and I will be spending 10 days in Tuscany. We've already booked 5 days in Pienza. Our TA has selected a couple of other places to stay for 5 days. 1. Villa Marseli/Cortona, or 2. Villa Porta all'Arco/Volterra. Both villas are just outside of the towns but within walking distance to enter. Villa in Volterra is within 3 min. walk to steps leading into the town. What are the steps? Many? Steep? Although I can walk forever, I have a knee problem that makes climbing stairs slow and a bit difficult although not impossible. Any thoughts on either area/which would be the most interesting of the two. Thanks for any help.
