We are planning 4 months in Italy in 2014 and want to spend one month in May in a villa or agritourismo in Umbria as a base for exploring Umbria and Tuscany. We don't want to be too isolated - prefer to be able to walk into a nice town or be in the town itself for restaurants, markets and sights. Looking at Perugia or Siena (larger options) or Orvieto, Cortona, Spoleto, Gubbio (smaller options - we don't want to be in a place smaller than about 20K population-places like San Gimignano or Monterregioni are good for a day trip for us!). Would love a villa or apartment and need sleeping space for 2 guests. Any ideas on towns or properties welcome!
