We have a 150m2 four bedroom, two bathroom terrace flat with a living room and kitchen. I should add that three is the bedrooms are not used frequently as we have a baby but the baby sleeps with us in our room. I am working full time in a very intense job and my husband also works. I ideally would love someone to do a clean and also look after our clothes (washing, putting away). We have a clothes drier. How long and how frequently do you think we need someone?
