Pietro and Alessia were gracious hosts. Pietro picked us up from the train station and welcomed me and my family to lovely Tivoli. We arrived before check-in time but Pietro allowed us to go to the flat early. Alessia informed us of the sites to see and gave us a list of her favorite restaurants. The flat is spacious and centrally located in the medival sector of Tivoli. It was perfect for us. Thanks Pietro and Alessia!
