Nescens Spa at La Réserve Paris, France

Best for: Medical-grade treatments

The swanky new Haussmann-style La Réserve might evoke a bygone era with its Belle Époque interiors and lavish antique decor, but its spa is all clean lines and modern minimalism. Developed in partnership with the Swiss medspa giant Nescens, the spa program has a heavy focus on aesthetic medicine, anti-aging, and preventive therapies. Treatments begin with an in-depth analysis by a Nescens-trained expert, who creates a personalized treatment for each guest, though standard treatments like the Signature Nescens body massage ($290) are also available. The spa’s biggest highlight? A 52-foot-long heated indoor pool—a rarity in Paris. Treatments from $180; 42 Ave. Gabriel; 33-1/58-36-60-60;
