Fodor's Expert Review citizenM London Bankside

High-concept, high-tech, and super-trendy, this Dutch budget boutique minichain has a unique selling point—nearly everything at the hotel is self-service, and that includes check-in and breakfast. Even the in-room amenities, from the blinds to the television, are all controlled via a tablet. The egalitarian rooms (all feature the same design) are small, but comfortable, with huge beds and wall-size windows. They're soundproofed, too—a big bonus given the busy location on the South Bank, not to mention the happening bar/workspace downstairs. The effect is more no-nonsense than no frills; or, as the hotel's website puts it, "absolutely no trouser presses, bellboys, or stupid pillow chocolates." It won't be to everyone's taste, but you'll look a long time before finding a better affordable hotel in such a good location.
