This is five minutes walking distance from the Olympia Kensington, where the London Chess Classic takes place.
High Street Kensington is the closest tube Station. Shepherd’s Bush, Holland Park, Barons Court and Earl´s Court are all within twenty minutes walking distance or a few bus stops away. There is also a station at Olympia but services are less frequent.
The Hilton itself is likely to fill up well in advance due to the London Chess Classic. It is the best, and the most expensive, hotel in the immediate vicinity.
The Lily Hotel is always popular with conference attendees. It is an easy walk away and much more affordable than the Hilton, albeit of somewhat lower standard.
The website for the Olympia (which is the venue for the London Chess Classic) also has a useful list of nearby accommodation.
