THE MANSION ON O STREET
Built in 1892, this Tiffany-windowed redbrick is an exquisitely cluttered maze of wood-panelling, paintings and secret doors. Accommodation (from log cabin to Playboyesque Purple Suite) hosts presidents and discretion-seeking celebs. Everything - from duvets to doo-wop LPs - is for sale, so you can shop after you drop. 2020 O Street (202 496 2000, www.omansion.com). Doubles $125 (£85).
