@Breccia0 The problem is that there may be many listings with the same name all over the world. Listings with the name Casa Palmeras can be in California, Costa Rica, Spain and many other places. So Airbnb does not provide search by listing names.
The best thing to do is ask your friend to get the web link to the listing so you can go directly and not even have to search. The web link looks like this:
www.airbnb.com/rooms/xxxxxxx where the x's are numbers unique to the listing. So, for example, my listing's link is this:
www.airbnb.com/rooms/4697622.
This should really simplify things for you!
