Frommer's "During the Cold War, the piano bar of the Central Plaza was a notorious meeting place for spies"
Oyster "The 101 rooms are simple, but modern, with amenities like Nespresso machines and minibars, but be aware that not all rooms have air-conditioning and some rooms will have been previously occupied by smokers"
Star Service "The adjoining winter-garden lounge is down a few steps and blazes neon to attract business at night"
