$250 sounds like a lot of cleaning, multiple hours of cleaning by one person for sure, of course depending on your location. But that really gotta be some mansion or your customers are really the absolute worst if that's always required. Meanwhile my friend who does this stuff changes the sheets and towels and wipes the tables together with some light vacuuming and that's basically it, only a few times per year he does a more thorough cleaning. And he does it by himself since he has reasoned that he wants to check the apartment personally every time it's used anyway and he can carry those operations at the same time since it takes something like half an hour to do so.
