Recently I flew on a very small town close to Polignano in Puglia. A very nice place called San Vito. There are a few restaurants so good to try here and the surrounding calm will take you away from your thoughts and worries. Of course it's great for the beach. Just in the north of this little town there is a tower where you can lie down and enjoy sun and sea with limpid water. If you want I can advice you a couple of wonderful restaurants here.
