Don’t have a top 10, but some things that teenagers/10 year olds might like are:
Panda Breeding centre, Zoo (Not brilliant, but cheap), Shopping in Chunxilu (and eating cool things Taikooli), Hotpot (essential experience for all ages), Peoples Park is good for a wander about and a cup of tea, Jinli Street.
As for Air BnB, I dont know, but you wanna be centre south of the city near a subway line. I’d say Tongzilin, Nijiaqiao, Sichuan Gymnasium area.
