The cleaning service cleans the common areas and the bathrooms. Make sure you leave your door open when the cleaning service comes by in case you have a private bathroom.
The cleaning tasks include:
Vacuuming the staircase
Cleaning the hallway
Cleaning the kitchen
Cleaning the bathrooms
Decalcify the sink and shower windows
Note! The house is responsible for washing the dishes upon the arrival of the cleaning service. It would be disrespectful to for example organize a party the evening before the cleaning service arrives, only for cleaning service to clean the kitchen and living room afterwards.
