My ancestors were from Tufara, which is just a short drive from Celenza. When I was there I met a man who told me I could follow him to the cemetery. He ended up being a property manager, had the keys to the office, and looked through some books to help me. He showed me his father's grave, and come to find out we had the same surname! (although unable to find a connection)
From there he directed me to the municipo, and a man came out and greeted me. I had a copy of my family tree with dates and names and he asked to see it. He pulled out his licence and had the same name as me.

They were very funny about the language barrier, and completely welcoming (even posed for a picture with me). They opened some original birth record books which I recognized as a possible source of the Family History Center's microfilm. They also informed me that the records in Tufara prior to 1800 were destroyed in a fire.
It was easy to drive. The scenery is really so breathtaking I had to remember to keep my eyes on the road! I bought an Italy map for my gps which was pretty accurate with minor exceptions (directing me to drive up a clif). I had a Fiat 500 which got a lot of looks from people in town.
I stayed at the Relais San Pietro in Celenza, which must be the hotel you are referring to. I can go on and on about how great our stay there was. Beautiful place!
