On Dugi Otok, Villa Nai 3.3 is carved into olive groves above the Adriatic, an adults-only retreat where architecture, landscape and olive oil production are closely tied together. Its eight rooms and suites are cool, sculptural and understated, with stone, glass and muted interiors opening towards the sea or surrounding groves. The estate includes seawater pools, terraces, a spa, cellar and restaurant shaped by island produce, while the olive mill gives the hotel a distinctive agricultural identity within a quiet Croatian island setting.
