I can only add to what everyone else has said. Mario's apartment, and especially his terrace, is a stunning, magical, place. Every detail of the apartment is beautifully curated and designed. Mario was also very extremely helpful in providing local tips- restaurants, beaches, etc. We found Polignano itself to be a bit overcrowded/overtouristed for Covid times but all the more reason to just stay on that terrace and look at the sea (or drive a bit to nearby beaches). We were traveling with a two year old and she loved the apartment too. It's very well set up for a family trip. Thank you for a wonderful holiday!
