Location location location! This apartment is on a quiet street just one block away from the center of the commercial district. There are so many amazing restaurants and coffee shops in this area. We were there for a month and there a still a bunch we never got to. This area of Mexico City is simply beautiful and a wonderful place to explore.
The apartment is quiet, in an older building (maybe 60 years old) with thick concrete walls. The wifi is great, and there is a washer/dryer unit in the apartment that worked perfectly. We had some struggles with the hot water heater, but Zaneta sent over a plumber that helped a lot. The space is secure, with a double-door at the entrance to the courtyard of the building, and two locks on the apartment too. Not that we saw anything remotely looking like crime in this lovely area.
Alex, who lives downstairs, was always ready to help out at any minute, and Zaneta (though on vacation) was super responsive.
