Marco was an extremely gracious host with a beautiful apartment. He spent a good amount of time with us explaining the city and making recommendations on places to eat and things to see. He also helped us with transportation and visiting sites outside of Mexico City. I recommend staying at Marco's apartment if you're visiting Mexico City. The place is just around the corner from lively Roma Norte and a short walk from LA Condesa, and Marco will make sure you know where to go and what to do.
