Hotels in Mexico are rated through the “Stars and Diamonds” System, as decided upon by Calidad Mexicana Certificada A.C. or Calmecac (www.calmecac.com.mx). The hotel which meets the highest requirements earn five diamonds. This means that the hotel has top-tier infrastructure and that the facilities, services and hygiene meet the highest international standards.
Five-star hotels offer similar quality, but the level standards on service and detail of the room is lower than that of five-diamond hotels. Four-star hotels offer more basic facilities and services, with hot water and purified drinking water. Three-, two-, and one-star hotels have progressively lower standards.
In Mexico, you will find the familiar hotel brands and major international chains, but also a number of less familiar brands. There are also boutique hotels, so named because of their smaller size but higher service level standards.
All in all, Mexico's hotels will provide you with a “home away from home” as you enjoy the various wonders and sights in the country.
