    "Too Far from my work. But i like the schools and accessibility to the beach. Overall comparing to NC Charleston even Mount Pleasent houses are half in quality and so ugly houses not even breaks … with triple prices … and 30-50% smaller … Roads are not the bests … I am disappointed … But have to work here … so no choice !"
