Great Northern Hotel
Time Out says
From the swanky lighting and the hand crafted furniture to the sleek decoration, everything about the Great Northern Hotel oozes glamour and sophistication. The British Library is great 'n all, but King's Cross station is your gateway to the rest of London (or Paris if you hop on the Eurostar). A 24-hour front desk, free WiFi, Hypnos beds (very expensive, very comfortable) complete your stay.
