We show on our listings, as a self-catering apartment, we supply two rolls of TP, a bar soap, enough DW liquid to get you started, 2 trash bags, and 2 dishwasher tabs. This way we have set the guest's expectations and it gives housekeeping a standard to work with.
If we have a larger group coming in for more than a one-night stay, we may put in a couple more rolls. We always leave any toilet tissue that has been left by the previous guests under the sink.
