The problem with Air BNB is all the extra charges they tack on. You try to compare motel rates with airBNB, think you’re getting a deal, and realize you could have had a decent motel room for the same price or cheaper. And the motel cleans your room and makes your bed every day.
I’ve had good luck with AirBnB in Europe. Usually much cheaper than a nice hotel. But I didn’t need parking there and that can be a hassle in the US. Also, in Europe they have a much longer history of renting private apartments. You’ll find whole buildings where all the flats are rented by the night over there.
