Has anyone use Airbnb?

Hoping for something better then the Days Inn. any luck here?

I found a very good Days Inn in downtown Edmonton, Alberta, two years ago. Because I arrived by train, I was given an unexpected discount. The restaurant (no dinner, though) had good food, and there was a coin laundry on site.

There are several other websites that show good accommodations besides Days Inn. Some, such as AAA, require that you be a member to obtain the discounts offered.
