Bruce was very helpful & communicative prior to our visit. For an extra fee he arranged an airport pick up for us, and the driver, Ricardo, gave us a fantastic intro to the history of Mexico City on the drive. Bruce's colleague Cornelio met us at the apartment with a friendly attitude & answered all our questions during the tour of the apartment & building facilities.
The apartment is 1 block from Parque Alameda, and just over 1/2 mile from the Zocalo. A short (<100 peso) Uber from the Bosque de Chapultepec.
