[Same message as before; I changed only the title, to make it more clear what I'm asking about. I hope.]
My wife and I will be spending about 10 days, with a car, in Tuscany and Umbria next July or August. We want to visit at least Siena, Voltarra, Civita di Bagnoregio, and Assisi, as well as drive around and stumble upon other interesting places. We're reasonably-vigorous seniors; we like lots of walking to experience authentic town life, history, some art, and good local food. We're thinking of staying in one place for 5-ish days and then moving on to another; in each we'd likely hang out in town for a couple of days and take a couple of day trips by car. (We could also overnight during one of the "day" trips.) We can spend up to $150/night for lodging but would prefer, obviously, to keep it lower. We'd like suggestions for the two places . . . and alternative ideas if you've got 'em. An agricotourismo is definitely a possibility. Thanks!
