Cotton House Hotel

A spectacular former cotton-guild building in the Eixample — Lázaro Rosa-Violán's design built around one of Barcelona's most photographed interiors, a sweeping spiral staircase. Request a room overlooking the interior courtyard; the spiral staircase demands photos, the terrace plunge pool is intimate, and afternoon tea is taken in the library. Summer for the pool, year-round for the architecture; book higher categories for terrace access. It is intimate rather than grand — a refined, beautifully designed hotel where the guild-building bones and the famous staircase set it apart, with service to match. For architecture, atmosphere, and a central Eixample base, the spiral staircase alone makes the case.
