"This year-old, 162-room boutique hotel is housed in a beautiful neoclassical building and is the perfect example of how perfectly contemporary design elements—minimal furniture, museum-white walls, and lots of high-tech gadgetry—can lend themselves to a traditional space. The rooms are kept purposefully stark, with the street-facing windows and scattered pops of grey serving as the sole decorative elements. Upstairs, on the 360-degree terrace, you’ll find the small but incredibly Instagrammable Sky Pool and the Nice to Meet You restaurant, which in addition to great tapas, cocktails, and music, offers the most intense sunsets and panoramic views of the Madrid skyline. Also worth mentioning are the very reasonable room rates. "
