@Matthew285,
The link is not an Airbnb one.
@Simon283, if you haven't already done it you should also report the link to whoever you got it from.
Just because "airbnb" is in the link doesn't make it legitimate. It has to be of the form airbnb.com or airbnb.ie for Ireland, airbnb.ca for Canada etc.
Links to particular listings are of the form airbnb.com/rooms/xxxxxxx where xxxxx is the listing number.
Using an old laptop I went to the link provided and while it looks like an Airbnb page it behaves differently to a genuine one when you scroll down to the map and it doesn't have all the layout elements of a genuine page.
Steve.
