It depends on what caused the mold growth. If the growth is only on the surface, the drywall is not damaged, or otherwise impacted, you can clean the growth from the surface. Baking soda can be used as well as a vinegar solution. I would not recommend using bleach.

Does the wall have moisture problem from a leak or something like that? Usually there is a reason why the mold is growing. Also it can be from high humidity.

Im sorry to hear about your experience. Unfortunately we put so much trust in these establishments and often forget that these things can happen. The remedy was unacceptable, I would have documented the condition and send an email to the corporate office to file an official complaint. Often the corporate office is unaware of what goes on at the property level. Its always a good move to notify them so they can remedy the issue. If it happened to you, it can happen to another guest at the same hotel.

Good morning, sorry for the delay in responding back to you. Has your aunt reached out to any mold assessment inspectors in her area?

We complained to the front desk and their remedy was to place a comforter over the mattress and under the flat sheet. We cut our vacay short and left. Our respiratory and digestive issues have since subsided.
