This apartment is a wonderful place to have as a base to explore Mexico City. It is perfectly located in the heart of Condessa near many wonderful parks and places to eat. The set-up of the apartment complex is very safe and convenient (a "doorman" lets you in) and they are welcoming and kind, as was the very-helpful host who met us at the apartment for an overview. The actual apartment is bright, spacious and has a "happy" decor of modern-Mexican design.
Two things people should know: The apartment is up two flights of narrow stairs that might be difficult for some people to navigate. Also, at times we felt like we were sharing the apartment with the neighbors; we could hear everything that was happening in the ajoining apartment, including the tantrums of a very vocal child. All was very quiet at night but day-time siestas were a no-go.
