Citizen M (M for 'mobile') is a new concept for those who want luxury on the cheap.
This is not surprising when you consider that its Valley Wing alone offers a high level of luxury, personalised service, a minimum of 50sq meters of space and floor-to-ceiling windows (some with stunning panoramic views of the city).
Add to this the CHI spa – dedicated to 'restoring balance and harmony to mind and body' – and two stylish restaurants (Nishimura and Blu Lobster) offering a range of cuisines from traditional Asian to the latest international favourites and you start to understand why this hotel is grabbing so much attention.
