The host, Marco, was wonderful. Extremely communicative (in English) and flexible with respect to our travel arrival with friends, as well as our departure. He had lots of fantastic recommendations, too.
His apartment was in a great location for us - we were four adults wanting to experience some of the culture and sites CDMX had to offer, and it was perfect. It was nearby to Euro- or US-quality coffee shops, bars and restaurants. Couldn't believe how much great quality at low prices we could get here. The apartment is in Roma/Condessa area, which is like the Montrose area of Houston - everything "walkable", and completely safe. We'll be back, for sure.
