Firstly this place is in an excellent location!!! We booked Marco's place not really understanding Mexico City's layout too well. The flat is near to Roma Norte (walking distance) to all the cool bars and restaurants.
Secondly Marco was a supreme host. Always ready to help and offered tips where to go accommodating them to our preferences. He is an art lover with great taste in restaurants. This was helpful for me and my wife navigating the city because neither one of us really speaks Spanish.
Thirdly Mexico City is one of the best city locations we have visited. We stayed for 6 days. City feels safe and has a very hip Berlin feel to it.
