thanks she is in my storage room
There should be an option to ask Roderic to make a room for Athia. The option isn't there until Athia has moved in.
Just a heads up about a thing that has tripped me up a few times. If you don't trigger her to make you a dinner, you can give her a good meal each day which will raise her affection, you only need to get it to ten. That way you can do it on your own time and not commit to eating at your place at 4 to 6 pm.
But in order to get her to cook you have to make sure the fire under your pot is lit, and then when you talk to her and she asks for food, you tell her its her job to cook.
Also, make sure you have taken a bath so you know its up and running, then you need to tell her that she can take a bath.
Where I have forgot how it works a few times is that I have taken a bath, then followed her quest up to where it says to take a bath with her, but she never gets in the bath, it's because I hadn't gone to her room and told her she can use it.
If she is going upstairs after dinner instead of the bath, its because she hasn't been told yet.
Also, also, a lot of her late stage quest items require waiting a full 24 hours before its available without it saying to wait a day. Like after a bath it will say "confront her in her room" you can go to her room, and talk to her, but the actual confronting won't be available until the following night.
