We will be in Perugia Oct 6-10. I would like to stay in a hotel that is easy to access with a car yet allow us to walk to the historic center with little difficulty. We plan to use it as a base to see other towns as well. When I look at hotels I have no idea how to figure out their location. Is there a land mark I should use as a reference point? would Orvietto be a better place to stay?
