Extensively renovated in 2018, this 1974-built 137m-high monolith's 995 rooms are stacked over 34 floors. The best have sweeping city views of Paris' monuments, as does the refurbished top-floor bar. It's handy for attendees of the Palais des Congrès next door.
Doubles are 22 sq metres; some include sofa beds where children up to 12 years can stay free.
