I am looking at a short-term apartment very close the the Willesden Green underground (High Rd and Linacre Rd) for my 2-week research visit to the British library. The rate for a private studio is literally half as much as that of more centrally located flats/hotels I have looked at. This represents a significant savings for me. Is this area generally safe? I will never be walking alone, but I will be returning late at night. I generally consider myself a "street smart" person, being from New York City.
