We stayed at the Palazzo Piccolomini in Orvieto last year. This year we stayed at La Badia which is located in an old abby. The Palazzo Piccolomini has a new and old building so you need to decide which one suits you. We have stayed in both and both have advantages and disadvantages. The Piccolomini is in a great location witin walking distance of lots of restaurants and basically near everything you could want to do in Orvieto. Both times we stayed there our rooms were clean and sufficient. The staff has always been helpful.
