Ricardo and Marta were wonderful hosts. I felt so at home. When I was there, Marta was working so Ricardo took care of me. It was a wonderful experience. They have a lovely home and a beautiful outside patio for relaxing (or morning yoga). The wifi was good, the location perfect (close to City Market with everything one would want and 5 blocks from a metro).
They let me use the kitchen to prepare my meals and Ricardo made me a wonderful breakfast (with Cuban coffee) each morning. I highly recommend staying here when you are in Mexico City.
