Andy's place is simply terrific. It has everything you need to stay for a few days or a few weeks; the location is perfect - you are a few minutes from Lincoln Park which is surrounded by cafes (try Josélo, Toscano) and restaurants (try Loggia), each with a view on to the park. You are several minutes from Palacio del Hierro and Antara, which have everything for a fashionable shopping trip. Miyana has Soriana, which is a well-stocked supermarket, and a little further is La Comer/CityMarket for even more selection.
Andy is an amazing host. She makes you feel welcome immediately and is always available to answer any questions. Andy has made her place perfect for a short- or long-term stay. You will have a fantastic time visiting CDMX at Andy's place.
