We assumed that Southwest Airlines would offer reputable properties - wrong. They take you to booking.com, and the biggest problem with booking.com is that their properties are not vetted. Our money for a booking was taken, then we were denied entrance to the property after 10pm when our plane landed because of the fine print. On the second day of our booking, when we are let in, we find out that there was no key to the property in the first place, as a prior tenant had lost it. The door was wide open - and continued to be so as we were out and about. Additionally, we lost $150 on a deposit that the property wanted us to "zelle" to him - he didn't return it because of damage to the kitchen... there wasn't even a kitchen in the one room property we rented. Plus, there was no toilet paper, and no bath towels. Still, booking.com will not refund us the money for the first night or for the deposit. STAY AWAY.
(I have no problem with the airline itself - just the hotel booking)
