With a rich history as a 19th-century bathhouse and then a popular nightclub teeming with stars in the '70s and '80s, Les Bains reopened as a luxury boutique hotel in 2015. Situated in the Marais -- close to restaurants, bars, several top attractions, and four metro stations -- the hip property features atmospheric, design-forward interiors that include a moody lounge complete with chinoiserie stained glass windows, and a chic restaurant and bar. Staying true to its heritage, the hotel is home to a club (note that noise can be an issue), but a lack of spa facilities are a disappointment and the indoor pool is small. The 39 guest rooms are stylishly clad in soft hues, luxe materials, and modern comforts, while their bathrooms come complete with Le Labo toiletries, plush robes, and rainfall showers. Travelers might want to compare with the Pavillon de la Reine, also in the Marais, which has a full spa and fitness room, but it lacks an on-site restaurant.
