"This significant new arrival might be right on a corner of the Spanish capital's arterial Gran Vía, but with its discreet entrance down a side street, it still feels a bit secret. It's a topsy-turvy place with check-in on the sixth floor in the brilliantly curvaceous, open-plan reception-restaurant-bar Atico. This is a space made for lingering: decorated in rich charcoal, coral, and forest green, with velvet curtains, wingback chairs, a marble fireplace, and bookcases loaded with leather-bound tomes. Off to one side, there's a small balcony dotted with olive trees beneath which to eat churros for breakfast. On the other, there's a pergola-covered terrace for lunch and dinner, where the menu swings from the creative (upside-down red-tuna pizza) to the classic (perfect ham croquettes). It's overseen by innovative chef Ramón Freixa, whose restaurant at The Principal's sister Hotel Unico has two Michelin stars. The 76 bedrooms below this sociable scene have Jackson Pollock–esque artworks clustered above the beds and a palette of moody greys. Gin's the thing at the bar (as it is across the whole city right now): goldfish bowls of the stuff, tinkling with ice and splashed with tonic, preferably drunk at the rooftop Terrazza, with views stretching north over boutique-packed Chueca and south towards the Prado. This is the first really smart hotel to open slap-bang in Madrid's tourist hub in ages, and without a tour group in sight. —Ramsey Qubein" - Lauren Burvill
