I had a horrendous experience at my last airbnb accommodation, which was reminiscent of Fawlty Towers, where customers are treated like enemies.
I was accused of trying to sneak in a bloke overnight - he was my ex who I am still friends with and he wanted to use the loo before driving back to his own place nearby after we'd had a night out (both of us sober). I haven't had sex with him for 4 years and this was in a place where the room rate was the same for one or two people, so why would I bother trying to sneak him in?
In confronting us the owner was angry and out of control. Afterwards I spent the whole night locked in my room in silence, too scared to make a noise for fear of upsetting him again. As a solo woman traveller I felt extremely vulnerable and couldn't wait for daylight so I could get the hell out of the place, which was in an isolated rural location.
My ex told me not to bother leaving a review if I am worried about getting sued - as I'm sure they would have the resources - but I know they are going to undermine my reputation and I don't see why they should get away with their unpleasant behaviour.
I have written the review as neutrally and factually as possible and have hugely downplayed what happened. I'm just venting on here! 
They have lots of glowing reviews from scores of happy customers, many of whom I'm convinced were too afraid to write anything else.
What do you think? Publish and be damned, or wait for their review first and just write a neutral response to it to be on the safe side?
