I am an experienced housekeeper and happy to provide references!
I have two major philosophies when housekeeping:
1) "If you are going to do it then do it right!" I aim to please. I do a good job cleaning and it gives me satisfaction doing so. If you have a special way you like things done then just show me or send me pics/vid clips and I'm happy to oblige. It is your house or office after all!
2) "Your business is your business!" This means that everything in your space is subject to confidentiality. I do not care how you live your personal or professional life, I am just there to clean up!
Cleaning gives me a great level of satisfaction, I enjoy having a finished project that others can enjoy.
