My friends and I lucked into a random reservation at the Casa de la Luz for our first trip to Mexico City, and loved everything about this hotel. The one possible downside is the loud nightclub across the street, but that is only a factor on Saturday nights and doesn't affect any but the front-facing rooms. Otherwise, the simple elegance, convenient location, extremely kind staff, comfort and cleanliness, and delicious breakfast all added significantly to our wonderful vacation. Extra shout out to Jesus the concierge, whose warmth and hospitality made us feel instantly welcome and at ease.
