Best way from PVG into the city of Shanghai

I will arrive on a Sunday at 1450. I am a single traveler and my luggage is one backpack. I am staying in city center, Former French concession area at the corner of Wulumuqi and Wuyuan road =5 min walk to Changshu road station ,access to line 1 and line 7. What is the easiest way to get here vs the cheapest way? Thank you
