Well, I obviously wouldn't do anything when they are staying in the apartment but once they check out, I would use that to turn off the lights, air conditioner and close the shutters.
My parents have an apartment they rent and it's happened that guests forget to turn off the air conditioner at the end of their stay... It's not cheap to pay for that for multiple days not to mention that it's bad for the environment
