You're right (though I like the idea of villafying a town, which I suppose would mean filling it with large Mediterranean-style dwellings) but this sort of correction to something no one was in much danger of misunderstanding doesn't really contribute much and I suggest is best avoided unless (1) the perpetrator specifically asks for corrections, (2) there's serious danger of misunderstanding as a result of the mistake, or (3) correcting it gives the opportunity to say something genuinely interesting and relevant.
