Luxury condo. Short walk to the lifts!

First, let’s clarify the oven issue: it was fixed to my knowledge over a week prior, but no one used the oven since and it wasn’t until the day before that I was informed it wasn’t working. It was attitude she got from me. I was trying to explain to her that the longer she kept me on the phone repeating the known fact that the oven isn’t working, the longer it will take for me to get in touch with someone who can repair it. A simple concept she was not able to grasp. Second, housekeeping cleans the condo after each guest leaves and before the next guest arrives. The condo was cleaned a couple hours before her arrival and she requested an early check-in, which I provided at no cost. She did not come to me with any pictures or proof about these claims of uncleanliness. And, no one else has ever complained to me or VRBO or Airbnb about poor cleanliness. Despite demanding a full refund for her “experience,” she still stayed the entire 4 days (not a week - four days). She claims the oven is still broken and she served a raw turkey to her family. Yet the next guest who checked in the day she departed was able to open the oven door without difficulty and turned the oven on to 500°F, which it reached target temperature without difficulty. Do not blame the host or the appliance for your failure to cook a proper meal. Given her behavior, quick jump to demanding a full refund, and contacting Vrbo directly instead of working with the host first: this is likely a guest whose sole purpose is to find any little defect and exaggerate it to the point where she thinks she can get her way. This is a total textbook Karen and anyone would be a fool to rent to her. I did offer a refund. But she hasn’t responded to it.
