Slimy. And illegal in most large cities where Airbnb is popular. Renting out a whole unit in NYC when you're not present is illegal whether you own the place or not if you're not a properly licensed hotel or bed and breakfast. But, guess where Airbnb gets the majority of their revenue from in NYC? I'll give you a hint, it's not from nice families renting out a single room in their apartment and making dinner for their guests like Airbnb shows in their commercials.
