Eixample, Barcelona, Spain
Spain's coolest and most modern city, Barcelona attracts tourists from all over the world to its vibrant nightlife, excellent cuisine, beautiful Gothic and one-of-a-kind Modernist architecture, and laid-back beach vibe. And sometimes the best place to soak it all in is while taking a dip -- which is made abundantly easy in this city where rooftop pools are a staple at nearly every hotel. Check out our favorites in this slideshow: First up is this stunning sunken tub at the Majestic Hotel and Spa. Offering excellent city views and a lively bar scene right at hand, the Majestic's rooftop pool is one of the best.
