As an Irishman, it would be handy to filter homes in foreign countries to see if anyone who is same nationality as you. Better chance they might do an exchange and come home for visit.
I would think that the ’ favourite destinations ’ option would be enough. What you need is someone wanting to visit Ireland, does it matter which nationality they are?
From what I can see, (and maybe I am not using the app correctly). But at minute I do up a search and put in ‘reverse search’ and add Ireland. And it narrows options down.
My rationale on knowing who is an Irish expat just means that they should more than others want to frequent trips home so could bookmark in a tab etc to speak to in future. But uyes maybe preferred destinations does just the same
