Excellent housekeeper

We are family of 4 adults (my two sons are 23 and 24). We all work so are out of the house during day. We have one elderly dog. I am looking for someone quiet and discreet (small house), independent with meticulous laundering and housework. No need to shop or cook. I generally do not need helper after 5pm unless we are out and you need to walk dog in evening at 9.15pm. We live in a 1500sqft 4 floor house (no garden but some pot plants on terrace) by the sea in Sheung Sze Wan Clearwater Bay. Sunday and public holidays off - pay $5.5k. Own room on ground floor but have to share bathroom with one other. If interested text me. Good for someone who likes a bit of time to herself and likes the outdoors. I’d like a right fit (not for everyone) but if this sounds interesting
