My parents rented a house via this website and while the property was only mildly insufficient the owner was a nightmare and tried to charge us for a bunch (thousands of dollars) of BS work she claimed needed to be done and some missing items. However, when we explained the law to her she backed off. When we tried to submit an honest review of the nightmare owner they would not allow it saying that "your review does not meet our guidelines". After submitting several iterations attempting to become compliant we realized that the only way it could be seen as "non-compliant" is that our review was not flattering of the listing/owner.
This is not the first time we have had issues with owners and false advertising on these sites and neither case did VRBO/Homeaway do ANYTHING to help us but rather did everything they could to protect the owners!
Caveat emptor (buyer be ware)... these websites are NOT on your side!
