I want to start off with a positive which this was a very clean property inside and the furnishings were comfortable as well. The problem we encountered was the property was double booked through VRBO and another platform.
A few hours into our evening another family came to check in. The other family left and they were very gracious, finally locating hotel rooms to accommodate the 6 of them. In the mean time, I made numerous attempts to reach the owner as did the other family. Ended up contacting VRBO who reached him on a vacation out of the country. Not only did he not apologize or take ownership he blamed the mix up with VRBO when speaking to me, but with the other family he said I had no claim on being in the house despite my booking two weeks prior and having a confirmation, (The other family and I stayed in contact and he sent screen shots.) Not only did I spend a few hours during a family vacation trying to sort this out, there was a concern that the other family had the entry code. While they truly seemed like trustworthy people, it was prudent to address this. The owner said to disassemble the door lock and reset the code. Not an easy task.
Overall, I was really surprised that he did not even attempt to apologize. It most definitely was a security issue, fortunately the other family was remarkably kind. They, too, could have made the situation worse. It's the owner's responsibility to update his calendar when having multiple listings rather than shift the blame.
