My go-to method in an old apartment was extra long toggle bolts due to the extra thickness of the plaster and wood. Generally walls will be 1/2-5/8 inch thick but with all that material it can be over an inch thick..
Best bet is to try to find the studs or just put a toggle bolt through the layers. If you're hanging something extra heavy find studs.
