Good morning, Barcelona. The chaotic promenade of the Ramblas, the Picasso Museum, Gaudí and his Sagrada Familia ... all of these things can wait. First, take a dive into the Grand Hotel Barcelona’s infinity pool, a serene respite planted high above the hustle of Spain’s beloved Catalan city. This modern boutique hotel, ideally located in the heart of the lively and hip Born district, is such a tranquil escape, you might never want to come down. Just watch the action from above.
