From a recent review:
An extraordinary lodging, an historic wood warehouse space from 1300 AC converted into a comfortable, stylish and intimate apartment. The tufo walls, beamed ceiling, division of space and the built in storage make for a relaxed, homey feeling. Every detail is aesthetically well thought out to be reflective of Orvieto's remarkable history as a walled town, while adding whimsical and sophisticated modern touches.
It's a limitated traffic zone (ZTL) then just a few cars pass through.
