Here are the facts: 52 minutes before our agreed upon check-in time, I receive an email from the Host, stating that the unit is unavailable.

Verbatim: "I'm so sorry but something urgent has come up and the apartment is no longer available for tonight. I really hope you guys can find another good spot to stay and I apologize again!"

I will leave it up to you to determine if this is acceptable. In my opinion, I can't think of any reason as to why the unit would be unavailable, nor was I given any explanation. I will not be doing business with Holly or Airbnb in the future. Maybe you will have better luck than I did.
