I booked Christina’s house excited and ready for my trip to Dallas, TX. My guests and I arrived at the house and quickly discovered that it was not in the safest neighborhood. Once we arrived there was a man standing in the driveway. We got inside of the house and the house was clean. The cleanliness of the house and accuracy of the pictures is top tier; however once we arrived at the house to check in at 3:06PM the temperature within the house was 80 degrees Fahrenheit and the thermostat was set to 72 degrees Fahrenheit. I had quickly messaged Christina about the temperature and asked how to properly work the thermostat so that I was doing my part. After discussing how to work the thermostat correctly I set the temperature to 70 degrees Fahrenheit; however this did not make it cooler in the house instead it went up 1 degrees to 81 degrees Fahrenheit. I let Christina know and she let me know that she would be sending someone over to look at the AC to make sure it was properly working. My guests and I left the house at 4:52PM so that the maintenance man could check the AC system. She messaged me back around 5:50PM and to inform me that it had been “fixed” I told her that I would stay out of the house for another hour to give the house time to cool. My guests and I arrived back at her house at 7:26PM to find the house at 79 degrees inside. After around 2 hours of being fixed the AC dropped down only 3 degrees. I let Christina know that this was not going to be a comfortable stay and that I would like to cancel my reservation. She let me know that my guests and I were not being patient enough with the AC system, because the temperature outside affects the AC. I informed her that I also live in Texas (just not in Dallas) so I am a native to Texas heat and that no matter how hot it is outside the AC should not take 2 hours to drop only 3 degrees, and that this was an obvious sign that her AC system was not function properly. After canceling I opened as case with Airbnb Support to get a refund. Christina offered a number and claimed to Airbnb support that this number was fair because my guests and I had stayed at her house for 4 hours. I became highly upset when my guests and I only stayed for less than 2 hours (from 3:06PM to 4:52PM). She not only lied about how much time we spent at the house but about the functioning state of the AC. The house is extremely nice on the inside, but the neighborhood that it is in and the AC not functioning properly did not make this and enjoyable stay.
