I arrive at this vrbo and its 99 degrees outside feels like 118. I walk inside and thermostat reads 80 degrees. We make sure both are on. The one in the living area works, bedroom does not. We contacted host and we had already done everything we could to cool the place off, close blinds and curtains, check thermostat. We decided to go out, eat and explore. We get back later and its 79 degrees. Still very much too hot for san antonio. We contact her and she says that someone will be by to fix it that night. She gives us another room in the same building for the night. We move to that room and its warm in there as well, but within 10 minutes of turning the thermostats to 60, both areas were nice and cool. The next morning we go back to our old vrbo and its reading 75 degrees now, slightly cooler, but not cool enough for the san antonio heat. We went about our day and after dinner we went back and the thermostat was fluctuating from 73 to 76. It just wasnt getting cooler and I was so hot and sweaty and I just couldnt get cool enough and ended up having heat exhaustion with a migraine, vomiting and dehydration. My husband checked us into a hotel that night knowing that I wouldnt get any better in the heat of that appartment. Side note there is some music that plays at 9pm that is very very loud that isnt in the description so he careful with trying to get kids to sleep. Also if your tall like my husband 6.2 you wont fit in the shower standing up as the ceiling is very low.
