As a homeowner, I gave them one star. As a renter I would give them five stars but their site is bogged down since they are forcing us to go through their site and cannot go directly through email anymore. The block email addresses.
However for renting places it is a very useful site, even though you cannot email the owners directly, which I prefer We have found a lot of rentals using vrbo.
And because it is a paid site for the homeowners, who must pay A high fee to put in an ad, you do not find many scams on this site as opposed to free sites such as craigslist.
I have used this site for rentals many times and found nice places to stay.
