Casa Vieja, Mexico City $$$$
Concierge.com's insider take:
The modest name—which literally means "old house"—doesn't do justice to this ten-suite boutique hotel near Bosque de Chapultepec. There's no subdued mustiness here: The mansion is painted in bold shades of tangerine and persimmon, and the decor in the common areas, which includes flamboyant folk art from all over the country, is over the top (sometimes literally—don't miss the elaborate tiles on the lobby's vaulted ceiling). In the guest suites, which are inspired by the works of Mexican artists, every possible space is filled with hand-carved furnishings and well-chosen antiques. You might not be able to stay in Frida Kahlo's house in Coyoacán, but you can stay in the fantasy version here, done up in the colorful fabrics that she often liked to wear.
