Shanghai has two airports: Pudong (PVG, the big international one) and Hongqiao (SHA, closer to the city). Both connect easily to the metro. Here's how to reach your hotel without speaking Chinese.
The Maglev train (磁悬浮) hits 300 km/h and gets you from Pudong Airport to Longyang Road in 8 minutes for 50 yuan (or 40 yuan with a same-day air ticket). From Longyang Road, transfer to Metro Line 2 to reach the city center. Alternatively, stay on Metro Line 2 all the way - it runs from the airport to People's Square in about 60 minutes for 7 yuan.
Hongqiao Airport has its own metro station. Take Line 2 east toward the city center (People's Square, Nanjing Road, Lujiazui) or Line 10 toward the French Concession (Xintiandi, Yu Garden). It takes about 30-40 minutes to the center and costs 4-6 yuan. English signs and announcements are everywhere.
From PVG to the city center, a taxi costs 150-250 yuan; from SHA about 60-120 yuan. Use the official taxi queue or Didi (English interface, upfront fare). Traffic on the Yan'an Elevated Road can be heavy - the metro is often faster.
Shanghai's charm is in the lane houses (nongtang) of the French Concession and the old town - and they are a maze of gates, alleys and dead ends. Street numbers don't follow a pattern. Save an imhere route from your metro stop: each step is a photo of a lane gate, a plane tree, or a corner bakery, so you walk straight to the hotel door without reading a single Chinese sign.
