Please help me the best solution to go from Pudong airport to the Bund riverside hotel.

In the airport, you can take the subway line 2 to East Nanjing Road. Take the Exit 6 and walk about 450 yards, you will find your hotel. The walking route is like this: Get out of the Exit 6 and walk forward to Middle Henan Road for 160 yards, then turn left to enter the East Beijing Road. walk another 150 yards, you will see the hotel.

If you have many luggages, it is also fine to take a taxi for a direct travel. It takes 40-50min and costs CNY170-180.
