My friend and I loved this place so much that she tried to talk me out of writing a review so we could keep it to ourselves. It is lovely, with a spectacular and very convenient location, and comfortably furnished for relaxing and enjoying Polignano. The services provided by the nearby bed and breakfast (luggage storage, extra toilet paper, help with check-in, restaurant suggestions, daily cleaning, and a large and tasty breakfast) really give you the best of all worlds.
Giorgio had someone meet us at the train station, in a rickshaw, which wasn't strictly necessary (it's about a 15-minute walk) but was very much appreciated. The bed is very comfortable and the kitchen/bathroom facilities perfectly functional. One thing to keep in mind is that the gorgeous private terrace is literally right next to the popular public one - as in, you're basically standing right next to everyone with a little fence between you. Half the terrace is visually private, but not at all in terms of sound. We didn't mind at all and thought it was fun, but thought I should mention it since it was a bit of a surprise.
All in all, a lovely spot and one I'd love to return to someday. If you stay here, you won't regret it.
