It really depends on how you have described what they are getting. Have you advertised an 'entire home;' or are they just expecting a shared space or private room, and you happen to be away.
Do they have full use of all bedrooms for example? If so, then you would expect to have cupboard/hanging space cleared for use.
Bathrooms - you would expect these to be fairly clear of personal items like toothbrushes, razors, etc...
Kitchen - probably less of an issue in that they may welcome being able to access basics like salt, oil, pepper, tea/coffee. I think I would expect the fridge and freezer to be empty and clean.
All comes down to what their expectations are and what you have described.
