Thank you for your comments, however, it would have been important to ask me about the washing machine, since I see that you simply did not know how to use it.
For a person who has allergy problems it is really difficult to sleep in rooms with carpets, no matter how clean they are, as well as the bed linens. My suggestion is the next time you need to rent a property more suitable to your allergy problem.
On the other hand, I suggest you leave the property when you rcheck out cleaner than you left it. If your problem is extreme cleaning, it was not like you left the property which was quite dirty and full of garbage bags of several days, abandoned in the laundry.
