We arrived and the house was 88 degrees inside with one small fan on in the living room. I contacted the host and she told me that her "housekeeper shut it off cuz the previous guest they were 3 old ladies and they had the heat on 87 the whole week they stayed" and "it may take a little while to turn it back on". It was 90 degrees outside, that explanation makes no sense as, the air should has been turned on, instead of off by her housekeeper, and ready for renters when we arrived. I had a family of 6 staying there, that consisted of 4 children, this was a very miserable night of sleeping. The description on VRBO website states the house has air conditioning. The following morning the thermostat read 86 degrees. Now I tried to open windows as it was cooler outside than in the house. Some windows would not open and the others had a second pane of glass instead of a screen, so I could not air out the house, nor did we have proper exits in case of an emergency. That was when I attempted to go out to the back yard and look at the air conditioning unit to see if it was turning on, but the back door was not operational and unable to be opened AT ALL. Which the host was aware of and confirmed that day that it doesn't open. Again, a safety violation. So now we are sitting in an 86 degree, stuffy oven of a house, that we only have one exit out of. UNBELIEVABLE! I contacted the host again and made her aware of all of my concerns , including the cleanliness of the home, dead bugs on the table, spider webs and underwear hanging on the back of the bathroom door. I requested a refund for the second night, as there was no way I was going to allow my family to stay there. The host agreed to this refund initially, but changed her mind, only after I had left, she had fixed the air conditioner and I contacted VRBO for a refund. Although, I do appreciate the hosts response and that she apparently was able to get the air conditioner fixed, however, I was not going to keep my children there and the host agreed to a refund. I am disappointed in the condition of the house and the lack of responsiveness or integrity of the owner. I am also disappointed in VRBO to allow this kind of rental to continue to rent to others. I am concerned about the safety of this home. DO NOT STAY HERE, IT IS NOT SAFE IN THE CURRENT CONDITION!
