I'd rather have longer stays than shorter ones. Shorter stays means more work, communication, cleaning etc...
We stayed at a really nice ABB last year for one night. Knowing the work that goes into preparation we discussed with the owners the viability of one nighters and they were inclined to agree that longer stays would be a better option.
It would ultimately depend on your local market and your listing. If there were lots of one night transients then it might be beneficial to streamline your listing to make accomodation easier to turn around. It would also be easier for one nighters if you rent a room instead of an apartment so the answer would need to relate to your circumstances.
