Pros;
Little apartment for max of 2 people. Very nice view of Chapultepect castle.
Cons:
Traffic noise, extremely bad. The place is located right in front of a elevated highway and street level traffic from which the none stopping noise from vehicles - private , commercial blowing their horns and the never stooping sirens from ambulances and police vehicles ( day and night) made sleeping very difficult, even with ear plugs on. In top of that the bed was very bad, it felt like you were sleeping in top of a steel table.
On the last night we stayed, we heard some four to five popping shots coming from somewhere near at the street level, and the following morning we saw some 8 police vehicles parked in front of the our building and wrapped around the corner. Member of the police went inside our building. This last statement had nothing to do with the neighborhood which is a nice one ; Condesa. We walked the neighborhood many times and felt safe.
