We have a modern brand new duplex style property, just over 1 yr old to share. We very much value privacy and are also very relaxed and easy going as well, and your room is a massive 4.5x4.5m furnished room with aircon and ensuite, and there is a separate entry with your own door code to enter the building. Your "duplex" half is separate from the owner's who lives on the ground floor (so unlikely to interact much but on hand if you want to chat about anything:), and and a weekly cleaner is there to clean the kitchen, bathrooms and all common areas. Bills, wifi, netflix, printer/scanner and cleaner included, and on a "50Mbps" optus nbn network. I have a smaller spare guest room set up on same floor which you can try for one night to see if arrangement works for you.
Busy people... as far as I know the 1 person is always working and very tidy and quiet so not a party house.
