I wanted to use them. But there is an insurmountable problem. In order to get continuity, the same workers every time, you have to book well in advance. I would be happy to do that. But the problem is that while Airbnb pays the Host only after Check-in, Cooperative Cleaning takes the payment from your credit card on the day you book the service rather than taking payment on the day of service (as other businesses do for just about anything). This is very frustrating and obviously does not work. We often get bookings really far in advance, even a year in advance --- I cannot afford to pay for all my cleanings for the whole year in advance of getting paid by AIrbnb. And if I book last minute, I will get a different worker every time -- and I certainly don't have time to train each one in what to do.
I hope they correct this billing anomoly so that they will give with Airbnb. I don't understand why Airbnb has recommended them without their fixing this problem.
