I stayed there along with my students who where there while attending a Model United Nations. The staff was very helpful all the time and the location of the hostel is quite good, right in the middle of downtown, close to Zocalo and to the subway station. Many shops and restaurants nearby. The big minus is the extreme noise at nights specially when they apparently rent the upper floor for concerts. Plus, the street outside is full of life even late at night so sleeping might be difficult -a bad thing if you are tired after a long day-. The breakfast doesn't even worth some words -avoid it-.
