What's Edinburgh like to live in for young people?

Me and my partner are both 21 currently living 30 mins away from London. Everything is so expensive and there is really not much to do unless you want to go in to london.

I work from home and she is a student with a few years left to go and we have thought about moving to Edinburgh. Do you think it's worth it?

Housing prices are somehow cheaper than they are here and we don't even live in London which blows my mind

We've visited before and loved it but wondered what it's like to actually live there, anything I should keep in mind?
