Last week I stayed at one in NYC and it was honestly weird. The host wasn't there and just left the door unlocked and all the lights off - without saying as much in an AirBnB message. Some of the outlets did not have outlet covers, leaving wiring exposed etc...
Anyway, it's been clear for a very long time that the thing that you find from a hotel is completely lacking with AirBnB: Consistency.
On the flip side, should people be looking at AirBnB as a direct replacement for hotels? Obviously that is the operating thesis, but I think a better way to consider AirBnB is as a marketplace for Bed and Breakfast accommodations. All of the problems that are brought up go away if you think of it in that context.
