Somehow managing to be right in the heart of central London yet also on a totally quiet street, Sanderson conceals its five stars behind a cool steel & glass frontage of '50s futurism, which is only the start of its eccentricities.
They bussed in uber-designer Phillipe Starck to decorate the place, and apparently ordered him to make the lobby look like the minimalist fever-dream of an opiate-addled French monarch.
The place is brimming with mismatched design, with elements out of time periods ranging from the '60s, to the whenever-classical-portraits-of-dogs-were-a-thing era.
There are 150 rooms, with the bare minimum level of luxury including over 300sq ft of space, an internet-accessing flatscreen, 24hr room-service, and in-room spa treatments.
If you want to kick it up a notch, bigger rooms pack private elevator entrances, balconies, kitchens, living rooms, and beds you can't figure out which way to get into.
The whole building's wrapped around a Japanese Garden courtyard, whose giant stone hotdogs are backed up by vaunted Malaysian resto Suka.
Afterwards you can hit in-house drinkeries The Long Bar (it's not just a name, it's literally 80ft) and Purple Bar for bespoke cocktails.
