Penthouse for rent in Diagonal Mar i El Front Marítim del Poblenou, Barcelona city, Barcelona

Above the 15th floor, the duplex stops being a home with a view and becomes a habitable lookout. 185 m² across two levels, and a terrace that wraps the entire home with something no other unit in the building has: a private pool, suspended between the sea and the city. Downstairs lives the day: a double-height living-dining room that breathes outward, and a kitchen that does the same, both opening onto the terrace with barely a threshold. A bedroom, a full bathroom and a utility area close out this floor with the same ease. Upstairs, an open landing asks to be a reading corner rather than a corridor — the view has already made that decision. Two bedrooms, each with its own en-suite bathroom, take up the rest of the level: tall, bright, always facing outward. Illa de Mar crowns the Diagonal Mar skyline, between the sea and the city's largest park after Ciutadella. Metro, bus, tram and the Ronda Litoral a step away; the shopping centre, closer still.
