England

I'm trying to go to the Jane Austen Festival in Bath this year! I got two weeks off for the trip, now I just have to book it.  I plan to stay in Bath for a few days and see the country side then go to London for a few. Maybe even take a trip to Paris, just cause I can ;) Everything is looking good so far, but I'm having trouble finding a place to stay in London. Its so big, and I have no idea where to look. Anyone been there before, what areas do you recommend? Should I avoid some areas? Any advice would be welcomed.
