Non existent apartment in Berlin

I was traveling through Europe over Christmas with my wife, 2 children and my parents. Apartments in Vienna and Prague were wonderful. However, I got radio silence from our Berlin host once I had paid the deposit of $1000. Emails about location and arrival arrangements went unanswered. Contacted Airbnb through Twitter only to receive legal jargon and denials of liability in return. A day before our arrival in Berlin, I had to find a hotel ( 3 rooms) over the New year weekend, at huge expense. This was my first and last experience with Airbnb – never again.
