Can I legally break my lease within 30 days?

[Chodite]

I've been living in my Philadelphia apartment for just 2 weeks now. I am very unhappy with a number of things related to my new apartment. Someone told me that I may be able to legally break my lease within 30 days of my move-in date and still get my securtiy deposit + last month's rent back. Does anyone know this to be true or not? Thanks!!
