Very nice, stylish, comfortable stay in a great neighborhood in Mexico City. Very central to all the major destination neighborhoods. Francisco was very responsive and replied to any messages I had within minutes. He even met me in person and gave some local tips for my stay at the start of my stay. Overall I really enjoyed my stay at their apartment.
My only critique would be that it is fairly easy to hear noise from the upstairs neighbor. The neighbor was generally quiet, but expect to hear a little music or average living noise from his apartment at some point during your stay---probably unavoidable for big city living though.
