Flat Hunting

I've just been to see a flat this evening in London Bridge / Borough, with a view to sharing it and moving out of "The Flat From Hell." It would be sharing with Lawrence, who I met at Richard's party last night, who seems like a decent guy. The flat is a good size, though the layout wastes some space, and my room is about the same size as my current one.
Unfortunately there are several things which make me not want to take it:
Firstly, although the rent is really reasonable, it is still more than I am paying at the moment. There will be bills to pay on top of that and a large deposit, top that off with moving costs and extra travel costs, I just don't think I could afford it.
It would also mean that I would have to get up earlier in the morning to get to work, which is not a desirable thing at all.
I also really do not want to move away from the Barbican as I love this area.
I'm going to have to turn it down. Bummer!
