Moving to Cardiff

Hi all! Moving from Bristol to Cardiff next month and wanted to get your thoughts on a few things

In Bristol at the moment it is taking MONTHS for people to find a place due to high demand - is it the same in Cardiff?

Where is best area to move? I have a full time job with decent pay and my partner is doing a Masters at the uni. We’re in our mid-20s so preferably areas with young professionals and nice pubs and restaurants Budget is about 900pcm (not inc. bills)
