"The staff is part of the charm of this 41-room hideaway named after the sixth arrondissement where it’s situated. Le Six is tucked on a quiet residential street between the Luxembourg Gardens and the famed corner of Montparnasse where artists and writers flocked to the cafés in the 1920s. (Le Select was one of Hemingway’s favorites.) Jazz fills the lobby, which extends into a glass-capped lounge flooded with natural light. Starting at 183 square feet in the classic category, rooms come with Nespresso machines and L’Occitane amenities. Deluxe room no. 403, decorated with a leafy green wall mural above the king-size bed, is a top pick because of the balcony overlooking rue Stanislas. Four suites are ideal for families, with a sitting area’s sofa bed for the kids. An expansion is planned for the small subterranean spa, outfitted with a treatment room and hammam (privatized with each booking)." - Mary Winston Nicklin
