First thing we do is wipe down all surfaces, light switches, TV remotes, bathroom taps etc., and re-wash any cups/glasses. I used to be a "maid" when I was a teenager and would never trust a hotel room or holiday cottage etc to be anywhere near cleaned properly. I also observed poor cleaning practices, once on holiday when it was raining and we stayed in our apartment when the cleaner came in. She had one cloth and one spray with her, and went up to do the bathroom first, then she came down and started wiping the kitchen surfaces with the same cloth she'd just wiped the bathroom with - err, no thanks, we asked her to leave and didn't let the cleaners in for the remaining few days and did it ourselves!!
