Juan Carlos and Tom are great hosts. They helped us find a gym where we could exercise and they had great tips about where to eat and how to get around. They were easily accessible if we ever needed anything (like an extra towel or blanket). Their home is lovely with a fantastic roof terrace--a great place to unwind after a busy day. In January it sometimes gets chilly at night, and since houses aren't generally heated in Mexico City, it's a good idea to bring something warm to sleep in. We stayed there with our son, who slept on the couch in the living room, which he found comfortable. Because the apartment is on the ground floor, the one main window, which faces the street, is partially obstructed by plantings on the outside sidewalk. This creates a sense of privacy but also blocks the light or view. Still, the apartment was generally quite bright during the day and it was also very quiet at night. The apartment is in the neighborhood of Roma Norte, which is charming and full of wonderful places to eat, beautiful parks and some interesting shops. There were plenty of fantastic restaurants all around, starting less than a block away; there was also a well stocked grocery store nearby. We never walked to the metro because Uber was so easy and cheap--we could usually get a car right outside the door within a minute or two.
