Benjamin Franklin House
From Tardis Wiki, the free Doctor Who reference
Benjamin Franklin House was the house on Craven Street where Benjamin Franklin stayed during his extended visit to London in 1762.
The house was situated not far from the future site of the Charing Cross station. Margaret Stevenson was the landlady of the house. Later this house became a museum dedicated to Franklin, which is how the First Doctor was able to find it with Steven Taylor and Vicki in order to secure Franklin's help. (AUDIO: The Founding Fathers)
