SLS Barcelona

Every room comes with a balcony, and most of those balconies face the marina or the Mediterranean beyond. This hotel sits right at the water's edge, and the design inside leans maximalist, all bold lines and glossy surfaces. The pool deck turns into a full social scene by afternoon, and the beach is steps away for late-night cocktails. It is the kind of place that makes every other hotel feel like it's trying too hard to be calm.
