I stayed at Matteo's place for a short holiday break, off-season. Its location is perfect in the charming old city of Gallipoli -- secluded and quiet, yet with convenient shopping, fine dining, sightseeing and other leisure opportunities nearby. While not exactly at the waterfront, one can walk to the scenic Purità beach within 2 minutes. Spotlessly clean, spacious, well equipped. Great communication (both with the host, who responds in English, and his mother, who welcomed me in person -- in Italian). The only drawback was that the wifi wasn't working at the time (perhaps you should confirm with the host what the situation is when you book); however, Matteo proposed a reasonable compensation. I would have gladly stayed longer.
