Setsuko's apartment is well decorated and well located - Frontera is not the prettiest street, but it is only about a twenty minute walk to the heart of the Juarez & Condesa, or a short Uber ride to the City Center. There are some good restaurants and bars just a few blocks away on Obregon - nice and lively on a Saturday night - but the apartment is very quiet. We were two women traveling, and felt very safe in the neighborhood. The only drawbacks to the apartment were that there was no place for two people to sit and relax comfortably in the living room, and one of the beds was actually a very hard futon. Setsuko resolved this for us by bringing us a twin mattress which my friend put on top of the futon for the last two of our four nights. Setsuko was very responsive to messages and questions and has a great guide to the neighborhood in the apartment. Check in was a breeze and the building security was friendly. We very much appreciated that she speaks English, as we found that is pretty uncommon in CDMX.
