London area Intercotees,
I am doing planning for a potential trip to the UK. I plan to be in London for no more than 3 days before travelling north. My preference in London would be to stay in a bed and breakfast preferably on the west/northwest side of city center so I have a few questions:

- what are some of the better neighborhoods to stay in (safety, restaurants, transportation, etc.)
- any place I should avoid?
- any specific B&B recommendations?

Thanks for any advice.
