Business ProfileforGrand Welcome

I booked a vacation through Airbnb with grand welcome. The total cost was $1960.87. When we arrived, the welcome letter gave us the wrong address to pick up the keys, so it was sometime before we could get a hold of someone and find the correct location. When we arrived at the house, the combo for the lock that had been provided did not work And we had to call in for the proper code. When we got into the house the heat was not working. It was freezing, but we were told they could not drop off space heaters until the next day. For the first night we all slept on the living room floor next to the fireplace the next morning we went to use the hot tub and there was a dead rodent right next to it. We did not use the hot tub because of health concerns with the dead rodent that day the refrigerator also stopped working all of the food that we had purchased was in the refrigerator went bad because they did not send someone out until Wednesday so we lost out on all the food that we had purchased for the week. The first night we had to sleep on the floor in the living room to try and get warm from the fireplace. We couldn't use the hot tub because of the rodent issue. I was told by grand vacation that we would be rent refunded for our first night when we had no heat and then given a nightly discount after that since we had to use space heaters and move them around the property to keep us warm I was also told that we would be refunded for the food that had been lost, when I called in I was told that they would only refund us $254 they offered to move us to another property, however did not have a property with the same amenities. I asked if we could cancel the reservation to the lack of heat and the refrigerator not working, so that we may book some thing else via Airbnb however, I was told that our reservation was nonrefundable, regardless of the heat not working and the refrigerator not working and the safety and health issue of the dead rodent. I called grand welcome multiple times but they refused to honor their offer of a nightly discount and refunding for food
