Another opening with a rooftop pool to boast about is The Serras(www.hoteltheserrasbarcelona.com; from €238), a 30-room luxury hotel on the waterfront in Barcelona. You can’t do much more than plunge in the cobalt waters (the pool is 3m x 4.5m), but the heritage matters. The Serras once housed Picasso’s first studio, where he painted in 1896. More contemporary lures include the food, from Michelin-starred chef Marc Gascons, and the cool-white and Mikado-yellow interiors by Spanish interior decorator Eva Martínez. All this accumulated glamour will give the new Soho House Barcelona a run for its money when it opens in spring 2016.
