STR Cleaner wants more money for longer stays ???

[Jory Wilder]

I have an STR and usually book it out for shorter stays like 1-2 nights at a time mostly. My cleaner recently mentioned she would like to get paid more for longer stays that are like 4-5 days. Should I pay her more $ for longer stays like this or just pay her the same fee? My thinking is when there is a one night booking and the guest barley uses anything its not like she calls me and tells me to pay her less because it wasn't messy at all and there was barley anything to clean. I can see maybe if someone booked for a monthly stay. Just curious what was working for other investors? She does a great job and I want to keep her happy, at the same time I don't want to get taken advantage of since she gets paid per cleaning, she makes more $ when there are multiple stays within the week.
