I regret that my valued guest had a bad experience at my place, I have never had an issue with temperature before, this was a particularly humid day with unusual heavy rains, I did not realize that my guests called me at that early hour to adjust the temperature, I would have easily adjusted the air conditioning as I have a fully working air conditioning system.
My welcoming message has a paragraph dedicated to temperature control in which I ask my guests to let me know if they need the temperature adjusted to their liking.
My guest could have also easily come upstairs or knock on my front door and me or someone in my household would have attended to the issue immediately if she did not get a response to her voicemail in a timely manner instead of checking out. They could also have sent an Airbnb message which I would have surely received.
I do regret the incident and inconvenience caused to my valued guest but I believe my guest did not use all available options to contact me to provide a resolution to the issue before deciding to check out.
