We stayed in Le Grotte della Civita #8  It was incredible! It truly is a cultural, restoration project.  The caves are cozy, well lit, candles, soaking tub (I miss).  Their afternoon Aperitivo is lovely.  The breakfast is phenomenal.  The staff goes above & beyond to assist you.  Definitely recommend parking at their recommended parking area (they will come & collect you & your luggage). Thank you Sara, Paolo, Brunella  Emilia, Pasquale.  They will assist you with tours, actives as well
