Hotel Number Nine

Hotel Number Nine offers a sauna at the heart of its full-service spa, in a property on Via dei Conti, in the heart of central Florence. The sauna is open to all guests on a public access basis, paired with a steam room and dedicated massage and treatment rooms for a layered thermal cycle. A fitness center on-site adds an active counterpoint when energy returns. The broader spa at Hotel Number Nine pairs the sauna with the design-conscious atmosphere of a property right in Florence's most historic centre. The recommended sauna rhythm is the classic one: warm through, ease into the steam room, settle into the relaxation area, and repeat. The hotel's position is the real draw — the Duomo, the Mercato Centrale, and the Medici chapels are all within a few minutes' walk, which makes the sauna a natural close to a day on Florence's cobblestones. For a Florence sauna stay that pairs central-historic positioning with a serious wellness floor at boutique scale, Hotel Number Nine is a confident pick. The sauna ritual here is intimate, focused, and rooted in the heart of Renaissance Florence.
