Yes. I got a badass penthouse (shared) near the beach in Barcelona for $90 a night with my own personal giant balcony.   

Airbnb used to be the smart way to travel. It was just people renting out excess space they already had for side money.

 It was not supposed to compete with hotels. The booking and checkins were super informal.  

Wannabe landlords ruined it.

The wannabe landlord thing is absolutely true. Every mouth-breathing “entrepreneur” has an idea to buy property and make money via Airbnb. My family has a vacation property, and i noticed a ton of affordable cottages and cabins were all snapped up specifically for the Airbnb/vacation rental market, whereas it almost exclusively used to be families or retired people.
