We ended up not hiring the cleaning service company to clean our apartment coz it is not convenient for us to be there till they finished cleaning. If we are not there, I am sure they will delay their work and charge us for the extra hours.
Hubby managed to get one of his customers to do the cleaning for us for RM50 and RM10 of internet usage. He did a very good job cleaning the apartment all by himself! We do not have to be there to monitor him.
