What is the best way to find private owned apt?

I am looking for a 1 bedroom that allows dogs, what is the best way to find private owned apts? This seems like the better way to go, not only do I feel they have more character then the standard white wall apt in complexes but you seem to get more for your money(assuming the landlord takes care of the place) I have been looking on craigslist and in the newspaper, I was just wondering if anyone else had some better places to look. Specifically I am looking in the Allentown/ Bethlehem area….preferably Bethlehem and you would know why if you have been to Allentown anytime recently lol
