We have stayed in many Airbnb's over the last few years and Jo was the first time we've ever dealt with a difficult host. Long story short, upon arrival, we had to cancel immediately as the home that was described in the profile in terms of the number of rooms and 'dark window-shades', etc. was not what we understood from the listing.
After contacting her for some kind of on the cancellation, she told us to get lost. Fortunately, we found a great Airbnb home last minute, just a couple meters down the road which saved the day.
