The Palais Zahia is the best hotel I've ever stayed in, anywhere.
Everything about this hotel is stellar--the building's beautiful architecture and unique spaces, the Moroccan ornamentation everywhere, the condition of the rooms, and the various restaurant choices (some of the best Moroccan cuisine I've had).
The friendly and helpful management and reception staff stand out in particular. The cooks, restaurant servers, and room cleaners also contribute to the excellent experience.
