Looking for a room to rent in Cardiff

I'm looking for a room to share with a working proffesional (preferably female) to make it my new home. I work full-time, and I also on the path of changing my career, so I'm studying quite a bit too. I am more of a morning person, rather than a night owl, very tidy and I respect my home and the people I share it with. I don't smoke.
I would prefer to share the house with one, max two other people.
