What would you suggest on getting to holiday inn express gulou at west daqiang street from chengdu airport?

I think you can take the airport shuttle bus line 2 to reach the Tianfu Square first and then change a taxi to your hotel.
From Tianfu Square to your hotel, there is about 1.5km, so the taxi fare will not be so expensive even though you take two taxis. Since you do not know the routes to your hotel by walking, so the best method from Tianfu Square to your hotel is the best way I think.
Hope I can help you.

Nancy, thank you for the advice.
