I urge you to look into the Rushmore Hotel, on Trebovir Road, a minutes walk from the Earl's Court Tube stop. When I last checked, it was very good bargain, with big rooms, and a convenient location. (Soho, V&A, Knightsbridge, etc. all within walking distance) Earl's Court is ugly, but safe, and well located. My girlfriend lives in London (Earl's Court), and I have visited her about 25 times in the last three and a half years.

good luck Jonathan Chimene NY
