Which APP is good for booking tourist accommodation in Chengdu? Thank you.

If you book B&B, you can find some bigger platforms. The key is that there are many houses in Chengdu. You can find a national B&B platform, such as the Woodbird B&B application. There are many local houses, so don't worry about finding a suitable one. It's also guaranteed, and it seems that sesame credit above 600 is free of deposit.
