@Ben205 What does the written portion of the review say? A guest doesn't get to see their stars btw. You might message the host who left the review and ask them what happened. Two stars is pretty low so I'm guessing it must have been bad, whatever it was. I wouldn't take the chance. But it doesn't take much to horrify me, as a host, in the cleanliness department.
I should add, I have given a two star, for a guest who left a rather horrific mess in the bathroom and kitchen which required a lot of extra deep cleaning, and a general mess of personal stuff left behind, wet towels draped on furniture etc. I might have given a 1 star, but would reserve that for malicious damage. This guest was just horribly messy and thoughtless. He had promised me before arriving that he would look after the place as if it were his own! Now I know to ASK what that might look like 😨
