I never expect service when I'm using AirBnB. I expect a room, or an apartment, that I can stay in, while the host and I both stay out of each other's hair.
If I'm staying for a long term (>1 week), I suppose I'd take it for granted that I'd at least have access to the laundry facilities, if not be able to just dump my bedsheets in a laundry basket and be able to pull clean ones out of the closet.
