I list my vacation rental home properties on several different listing sites and I was having a problem keeping all of my calendars up-to-date. OwnerRez solved that issue. I like the ability to set up different emails that go out automatically after someone books. I also like that I am notified as soon as someone begins the booking process.
I like the ease of using the software. It does way more than I require.
At this point, there is noting I dislike about the software.
