The hotel does not have any self-serve laundry facilities. The hotel is not located near a town, so you will not be able to easily access a laundry facility.
The hotel does have a laundry service, you can see the pricing on the attached photo (pricing on the photo is in Pesos). On average it is about a dollar or two (USD) per item. Turn around time is about a day.
I might suggest packing enough clothing to get through the week and reserve the laundry service for emergency use.
