The Pool at Serras Barcelona

"Inside, contemporary additions abound; the in-house tapas restaurant, Informal, led by Michelin-starred Catalan chef Marc Gascons serves Mediterranean classics, while a rooftop terrace pulls in both locals and guests, thanks to a slick lounge area and infinity pool"

"The rooftop terrace bar and pool have spectacular views of glitzy Port Vell, while the hotel's fine-dining restaurant overlooks the old city’s palm-lined streets"

"There is also a rooftop terrace that offers dining facilities, a gym, infinity pool, and a sky bar overlooking the port"

"There's a romantic little rooftop terrace, with a plunge pool, a restaurant-bar, and DJ sessions on weekends"

"The rooftop, where Picasso was believed to have painted Ciencia y Caridad, is now a wooden deck with a plunge pool, olive trees and sensational port views"
