@Camille372 As Emiel and Ana said, the correct protocol if you arrive at a listing to find that it is not as advertised, or dirty, or otherwise unacceptable, is to first contact the host to see if they can do something to remedy the situation. If they are non-responsive, or brush off the issue, then you contact Airbnb. So that's what you should have done when you arrived. I understand that you didn't want to be left with nowhere to stay or have to traipse off to another listing, but if you make your displeasure or disappointment known ASAP, you are more likely to get an appropriate resolution. If you just stay at an unacceptable place, you probably took a hot shower, used towels and bedding, plugged your electronics into the electric, made use of the Wifi, and whatever else was there for your use. So expecting a full refund, rather than a partial one, isn't all that reasonable, unless the place was truly disgusting or seriously misrepresented.
