We LOVED this space; it was actually even better than we expected. After visiting CDMX, I really don't think you could find a place that offers more.
Marco's condo is down a quieter street but still just steps away from a beautiful plaza complete with a fountain (great for sitting and people watching), all sorts of restaurants (some the most noted in the city), bars, shops, bakeries. It's breeze to catch an Uber and the place is within a 20-35 minute ride to some of the must-see places (Museo Soumaya, Anthropology Museum, Palace of Fine Arts, Zocalo, La Cuidada market, Arena Mexico, Frida Kahlo House).
Marco's condo is spotless and very well appointed; we wanted for nothing. The rooftop deck is a great place to unwind after a day of sightseeing and Marco went out of his way to help make our stay memorable. I was travelling with my niece and the two bedrooms and two bathrooms also made it easy for each of us to relax into our own private spaces when we felt we needed that.
We were two women and not once did we feel unsafe wondering the neighborhood or the city for that matter. The people are so friendly. I would highly recommend Marco's condo and plan to return myself.
