Della Calza SPA & Foresteria

Della Calza occupies a former 14th-century monastery near Porta Romana, just inside Florence's historic walls and a short walk from the Boboli Gardens and Palazzo Pitti. The wellness center spans over 650 square meters, described as the largest spa in Florence's city center, built around a thermal pool and relaxation lounge set among Renaissance frescoes and medieval architecture, including Franciabigio's Last Supper.

Day passes are available, and walk-ins are welcome alongside bookings, so a visit doesn't require an overnight stay. During August the wellness center opens daily from 10:00 AM to 8:00 PM; hours for other months aren't listed here, so it's worth confirming directly. The site is reachable by car, with parking accessible on-site, and staff communicate in both English and Italian.

Beyond the pool and lounge, the property includes a guesthouse with Classic rooms and Suites, though those rooms are accessible only to guests who have entered the wellness center first. Dining comes via a bistro serving seasonal, lighter Tuscan dishes from noon to 2:30 PM, and a bar open from noon until 11:00 PM; both are likewise limited to wellness-center guests. The historic setting doubles as an informal museum, with frescoes and artifacts woven into the spa's public spaces.

Pricing sits in the upscale tier, fitting for a spa aimed at solo travelers and couples looking for a few hours of quiet in central Florence rather than a full resort stay, though an overnight option exists for those who want to extend the visit.
