TL;DR: We liked the house until it flooded with sewage. The owner was not responsive.
Around 9:15 a.m. we found clear water near the toilet in the main bathroom. I mopped and sent a message to the host, Marilyn, via AirBnb. When I hadn't heard from her in 15 min I texted her cell phone. An hour later I got a response from a "Fabby"(?) that she wanted a photo to show a plumber. I told her that I was out, but would send a picture when I was back, which I did. Fabby did not respond.
By 5 p.m., sewage was seeping into the main bathroom around the toilet and bubbling up into the tub. The house reeked. My husband mopped up 3 buckets of foul brown water. I called Marilyn's cell phone and left an urgent message. I called AirBnb and over the next 3 hours provided photos/videos, dealt with two non-working toilets and sewage in the master shower, found a new place to stay, and got my family packed & out. I got a refund. The owner still hasn't responded to me.
