Let this be said upfront: I love Airbnb. I have stayed at quite a few over the past year, and many have been fantastic experiences, and I'm sure I will stay at more Airbnbs over the coming years as well. However, I recently had a not-so-great experience with Airbnb. It really isn't worth going into the specifics about it, but it has lead me to develop my Airbnb Best Practices.
