Hi Lalsa and Welcome to HC. Congratulations on your first hamster Oreo.
I would bring her into the living room, it's important for her to get use to you and your noises. She will probably be nervous but in time she'll adjust. I've always kept my hamsters in the living room.
Should any noises upset her then reassure her by talking quietly to her and telling her she's safe and a good girl. I find that the tissue trick helps, so get you and your partner to stuff some tissue or toilet paper up your sleeves and leave for a couple of hours and then place in her cage, this will get her familiar with your scents, do this everyday for a week. She will sniff at it and will probably use it as extra bedding.
When it comes to hoovering, Use it outside the living room with the door closed so she can get use to it and only have it on for a short time. When you hoover the LR make it quick and then praise her afterwards. I've always found that the hoover frightened my hamsters so I do this and they get use to it.
