It may not come across as very appealing at first glance, but this plain, almost austere-looking building is actually home to a four-star hotel. Located a stone’s throw from Oxford Circus, its top floors are a green oasis in the very heart of the city. The interior is designed like a luxurious cabin and blends kitsch, eco-consciousness, fashion and above all good vibes. Needless to say, the décor features recycled wood everywhere, balancing out vintage with modernist touches. To top off the experience, the restaurant offers Mexican-inspired vegan dishes and organic wines. It’s true that there’s a bit of “insularity”, but everyone can breathe in this breath of fresh air that gives London one of its best addresses of the moment.
