I had planned on giving the owners of this property a good review until checkout. If you ever stayed at a VRBO, before checkout, you are required to do a small amount of cleaning before you leave the property. For example, taking out the trash, placing the dishes in dishwashers etc. One of the request was the removal of the bed sheets from the beds. Niether of the beds had mattress covers which was surprising. What made this so horrible was what we discovered after removing the sheets in one of the guestroom. It was the biggest, most disgusting stains you could ever imagine in the middle of one of the mattress. It looked like something out of a CSI episode! I could not distinguish what could have made such a stain, at this point, i don't want to know, but i was outraged that the mattress hadn't been replaced. Then to realize, my family member had been sleeping on it this entire time. I know they knew about the stain because the cleaning crew would have saw it while changing the sheets. I contacted the owners of the property as soon as we discovered the stain. No one ever contacted me back or apologized for allowing this to happened. That being said, im pretty sure the next group that rents this property will be sleeping on this same disgusting stained mattress. It doesn't take a rocket scientist to know, if you are renting your home out to various individuals, at least use mattress covers. I won't be back!
