Where should I go to find an apartment for rent in Tlalpan, Mexico?

Im from tlalpan, although I have never heard of that place, I suggest trying to find a place near Perisur and Bosque de Tlalpan, those are safe and expensive areas. I used to live in Coapa and it varies, most parts are nice. When you get to Mexico City get the EL Universal newspaper and look under "Aviso Oportuno" for appartments, but beware some are scams too but most aren't.
