 Two properties in Central London have been added to Hilton Worldwide's portfolio: the 583-room Mint Hotel near the Tower of London and Tower Bridge, now the Doubletree by Hilton London-Tower of London, and the 460-room Mint Hotel near the Houses of Parliament, which has been renamed Doubletree by Hilton London-Westminster. The two hotels are part of the eight-property Mint Hotel chain that Hilton Worldwide is adding. The Tower of London property has eight meeting rooms; the Westminster has 11.
