Working off St James' street and using it daily, i'd echo that.
It's now far worse than London Road in my opinion, just can't imagine it being a very pleasant area to live when there's so many better options nearby.
I'm looking to buy my first fairly small one bed flat, and my budget is £200k and there's not a great deal without going further out to Portslade/Soutwick/Patcham etc. (which I probably will do)
