I did, and I also did a whois lookup on airbnb-mm.com, which is registered by Airbnb Inc. And if you go to the domain it redirects to airbnb.com. *edit word and this, I did just check airbnb's site and it doesn't list that domain as one which would be a valid email domain for their consumer site information. But the whois and the redirect makes me think it is. However OP could forward the original message to report.phishing@airbnb.com and see what they say.
