Maria Jose has a great host, very communicative and helpful. The location was amazing -- we were attending a conference at the Sheraton Maria Isabel, and the apartment was 3 blocks away! Close enough to come "home" for lunch. There was also a great coffee+chocolate place right next door. We were a short Uber ride away from most of the museums and the historic downtown. Very nice neighborhood. Don't miss De Mar a Mar restaurant, across Reforma from the apartment.
The apartment is bare bones, but sufficient. The bed is very firm.
The only downside is the street noise. There are ear plugs in the bedside table, and you will probably need them (especially on weekends).
