I don't think it is fare you say that just because the visitors thought your flat was not clean enough... or because you forgot to have clean sheets at the apartment for example. It is a matter of expectations. We were paying for a service that we thought would be better.
And it is not true that my sister and her friend are not polite or friendly. And the communication was not good, why? Because both, me and my siter tried to contact you about the sheets so they could sleep covering a not very clean matress?
Sorry, but I think all airbnb users need to know exactly. There are many opinions and not all of them could be as you would like.
