I just got a flat for under 6k in CWB, and it's pretty nice. I looked into flat-sharing briefly, but it didn't seem like it was that much cheaper than getting your own place. And since I was leaning that way in general, I stopped looking. While trying to find a place, I looked at quite a few, some good and some not so good. The flat I chose isn't furnished (although most of them were), but I figured in the long run the lower rent will make up for the furniture costs (and I already have a few things that were free).
If you don't cook, then your options are even better! I like to cook and I wanted the ability to have a washing machine, so that limited my options. I looked at a few nice places (fairly spacious, sunny, clean, etc.) that I would have loved except they didn't have a cooking area. Most of the flats I looked at were in the 6-7k range, so I think anyone looking should be ok, but you might have to hunt a lot. And if you're able to go up to 8k then the flats are really spacious! Well, at least they seemed that way after looking at 100ft flats.
Oh, I also called a few realtors in advance to tell them what I was looking for, so that our first meeting was actually to go look at flats. Saves some time!
