As mentioned by another reviewer (after I booked) there is a portable a/c unit that is (barely) connected to a window with duct tape and cardboard, allowing anyone who wanted to open the window from the outside and enter the property. It also left it open to bugs and vermin. The fact that it hadn't been corrected since the earlier review made my family feel unsafe and we chose to leave after the first of three nights.
Other things of note:
It's much smaller than the listing would imply. There's no way 8 people could comfortably occupy it. It was tight for two adults and two children. There is an eat-in kitchen... with no chairs. There's a lovely backyard... with no seating. The living room is the only place to sit and it's small.
As always with these things - it's not so much what it is as how expectations are set by description and photography and this one has a big variance.
All of that pales in the face of the glaring safety concerns.
