We'd like to spend the month of Italy in a "home base" town somewhere in Tuscany or nearby, so we can do day trips or overnights to places like Florence, Siena, Assisi, Orvieto, etc.
We will have a rental car and want to rent an apartment or small house/cottage for entire month of August if possible -- preferably in or near a smaller town, and not in one of the busier or larger cities (for reasons of driving, cost, too many people, etc). We want some place that would be pleasant for us to hang out in much of that time -- we won't be out "touristing" every day but doing some writing and relaxing.
If anyone has either general suggestions of places that would make for a good base or specific apartment/house rentals or agencies to source them, we would love to hear them. (Our housing budget is up to about $100-120/night.) Also any general advice if you've done something similar.
Thanks much!
