The place is charming. We were greeted by Nani, who gave us some good tips for food and beaches.
The terraces (!) are a real joy. Don't expect to do any serious cooking though, because the kitchen is tiny. We loved how small and windy the house was- it gave it a lot of character, but you have to be comfortable with stairs. It's on a really quiet street, but close to everything. All in all, if you're considering staying in Polignano a Mare, I would wholeheartedly recommend Enrico's place.
