Alex & Ricardo have a cozy and charming place, and are great hosts: welcoming, attentive, helpful, and keeping their entire place very accessible (all is shared), clean, quiet and organized. I found their apartment a great place to relax & rest, work (fast internet), and explore the area. The room I stayed in is large, sunny (it also has good shades), and quiet, and its private bathroom is one of the biggest I've enjoyed in Mexico City. I would wish to stay any time again. Well done, friends!
