There is no direct metro could be used. It is suggested that you take shuttle bus Line 5 and get off at Shanghai Railway Station. The hotel is located about 2km away from the bus stop, so you could walk there easily.

Of course, considering the complicated situation around the railway station, you could also take the metro Line 2 from Shanghai Airport to the People's Square. And then, you should take a taxi to get to the hotel in 15 minutes.
