Spent a very enjoyable two weeks at Norma's place in CDMX!
Apartment is in a residential area and easy to find. About 20 mins walk to the Angel of Independence area and a short Uber ride or metro trip to other tourist areas.
Within a 5-10 min walk in the area there's a supermarket (Aurrera Bodega), a bakery (Pan Artisanal), some coffee shops, 24h OXXO, San Cosme metro and mercado, and a taco stand across the street.
The apartment itself is fantastic. The things we enjoyed were: 24h security at the front door, large balcony, rooftop terrace, washing machine, full kitchen, fast internet.
Norma has really thought of all the small details that make for a comfortable stay here and was even kind enough to have someone come clean the apartment mid-stay.
Would definitely recommend!
