The Zetter Hotel in London is everything we love about boutique hotels. They are well designed, accommodating and every time you get a new experience just by moving one room down. Here are some words from management: Each and every one of The Zetter’s 59 rooms have been individually designed in a quirky vintage-modern style, with state-of-the-art in-room entertainment and technology, a dedication to cozy comfort and an almost obsessive attention to detail. That said, as in life, the more you spend, the more you get.
