Great location, right near Polanco, Reforma, Roma, Condesa, Chapultepec park. I walked absolutely everywhere. Quite new building with 24hr polite doormen.
I stayed a month and Leticia is a wonderful host who every so often checked all was going well. There was a small problem with the fridge that she immediately got someone to repair. She arranged cleaning.
I highly recommend this apartment as a base for your Mexico City visit.
