Could anyone recommend how to best go about reaching grand hotel chengdu from the airport?

Is your hotel located at no.168, West Yulong Street? If so, you can take the airport shuttle bus line 1 to Provincial Stadium Metro Bus Stop. Then you may walk about 50 meters to Provincial Stadium Metro Station and take metro line 1 to Luomashi Station, Exit F. Upon arrival, you may walk about 100 meters ahead to find your hotel.
