Ostuni is fantastic.
Also, a good base for visiting Lorcotondo, Alberobello and Polignano a mare.
A must see for people travelling southern Puglia.
The apartment is in a great location. Just 5 mins from the centre.
The streets around the apartment are very narrow, so be aware if you are renting a car, you will need a small vehicle and it may get scratched (shared through personal experience).
Highly recommend Pilone beach.
