If you say it and the company in question complains, then stop saying it (in that situation the legality doesn't matter as it is a case of BIG v small), otherwise as long as you are not the "airbnb" of a market that airbnb might be in (or want to be in) then you are probably okay... maybe... don't ask a lawyer though, they tend to freak at this sort of thing.
