@Laura7046 There are many different views on this. Some charge nothing (just like you don't charge separately for heating, lighting, finance payments etc). Others charge an obscene amount, others the actual cost of cleaning and linen washing.
There is no right answer. High cleaning fees can annoy guests and encourage them to leave the place untidy. Also a high cleaning fee encourages guests to be picky on how clean the place is.
We charge just the cost of laundry and our nightly rate pays for our cleaning efforts.
A good start is to lay out all your costs and then calculate a nightly rate/cleaning rate with a reasonable profit. Compare this to the top down approach of being competitive with similar local listings. Then set your prices at a reasonable level whether for cleaning or the nightly rate
Hope this helps your thinking.
