You get your own butler. That's what you need to know about the Chatwal. About five minutes after you've arrived in your room, a liveried staff member will arrive at your door, introduce themselves, and offer their services. In our case, Kate and I were going to the theatre that night, and our (female) butler offered immediately to have our dresses, crunched in our luggage, steamed and ironed for our smart night out. There's also an extravagantly expensive spa downstairs, and a bar (that seems to attract a rather brashly wealthy clientele) that serves 1920s cocktails. There are remote controlled toilets that will rinse your bottom from every angle and which terrified the hell out of my poor sister. But the real reason to come here is the design: art deco, reimagined for the 21st century luxury market. It's extremely pricey. But then, true luxury is, no?
