If you can tidy up, pick up toys/clutters, clear the sink and wash the dishes prior to our arrival we will be able to maximize our time on cleaning.
Have a designated area or container for any trinkets of stuffs and Knick knacks we find while we clean, a small box or a drawer.
We strongly suggest providing your own vacuum cleaner. This will avoid cross contaminating your floors if for instance, your home has kids and does not have pets and the vacuum cleaner that will be used is used in a home that has pets, this will most probably cause health problems, and that is what we want to avoid.
