I appreciate the fact that we can edit our individual listing´s URL to make it as short and simple as we can, but as i have two listings, its better for me to share my "Pro Marketing Page" were my two listings appear, BUT ITS TOO LONG and i dont see a way of editing it.
You can create a custom link outside Airbnb if you own a website (or even a domain name) and redirect it to your homepage (called for some strange reason "pro marketing page" by Airbnb).
BTW why is it to long:? A URL shortening service can shorten it
