My friends and I reserved an apartment through Airbnb two months in advance. When we arrived, the room turned out to be a scam. It was already rented to another group. Airbnb did nothing to help us find a place to sleep and did not take our situation seriously. They stranded 3 young females in a foreign city and are refusing to refund the amount for the nonexistent apartment. DO NOT USE Airbnb.
