I'll preface this by saying that AirBnb lies about its prices/night, and that really suck.
Having said that, I really really don't understand the other criticisms against AirBnb here. I travel a lot, for leisure and work, and I constantly stay at AirBnbs and have been for years.
Here is how it compares with hotels for me:
* I usually can't remember any hotel room I've stayed at (unless it's the marina bay sands), whereas I remember every single AirBnB I've stayed at.
* When I stay in an airbnb for tourism, I feel like I lived a bit in the city, never get that feeling with a hotel.
* Pick up never has lines, and is often pretty straight forward (they have more and more of these locks for self-checkin)
* The location is always better for the price, I've heard people saying otherwise, but I've travelled all over the world with AirBnB and always found a better place for cheaper. The bay area was pretty hard, but I switched to a room at someone's place (instead of the whole place) and I ended up staying in insanely nice places. (I definitely recommend trying this, it's always much nicer and I seldom run into the people living there.)
* AirBnBs have a kitchen
* I overall find hotels to be dirty. There's something about them that I really don't like. Unless the hotel costs a LOT of money (again, Marina bay sands So yeah, I don't buy the AirBnB has failed thing, because I'm a heavy user.
I might be wrong, but I hope not because AirBnB going bankrupt would be a real bummer IMO.
