i am planning a trip with my sister to Tuscany or Umbria in May. We will likely be driving from the Netherlands to Italy and back and will have about 10 days in Italy. We prefer one base location, at the most two because we don't want to pack and unpack. We also would prefer to stay somewhere in the countryside. I have been to Florence and Rome, not sure if my sister has those on her 'must-see' list Any recommendations?
