Looking to find shared accomodation in South Wales

I am looking to find accommodation in South Wales, with access to Cardiff. I currently live in Blaenau Gwent with my brother, and have been here for 9 months. I have a Labrador who I must consider when finding a place to rent, he's well behaved and will be solely my responsobility. I work full time, doing an average of 60 hours a week, and study part time once or twice a week in Cardiff. Would love to find a professional with a similar busy schedule. Must be clean and considerate.
