This is what I do for a stand-alone studio:
If a guest stays longer than 7 days I let them know I clean Mondays between 10a and 12p. I change the bedding, change out the towels on the rack, do light housekeeping (replace soap, refill shampoo, clean toilet, clean shower pan, wipe down kitchen surfaces, start the dishwasher) but that is all. I am not a maid. They pay a cleaning fee once. I don't clean more than that. Cleaning fees are for cleaning up AFTER that guest. The minimal cleaning I do while they are there is more so I know how things are and see if there is damage quickly enough to take care of it.
