Time will tell, won't it. However, in spite of forecasts of how AirBnB will improve booking rates, at the moment, they are charging a LOT more, and the consumer (aka your average Joe, and the rest of the world) will pay more for housing but get no added value when booking through AirBnB. Kinda like paying for drinks in a side street "bar" in CUC while the locals are paying in CUP...
We shall all see, won't we. Glad I have booked my casa and am taking my sons now instead of waiting for the changes (improvements??) in 5 years. It isn't the Cuba of 10 years ago, but...
