The hosts on Airbnb don't get your credit card info...Same as, you know shopping on Ebay.

I just moved across country. I stayed at 3 different places of Airbnb over the course of 2 weeks while I looked for a place with roommates off Craigslist. Each host was great and I never felt anything but safe. The only reason I stayed at multiple is because they had other bookings coming in so I couldn't extend.
