Our family of 4 (mom, dad & two 19 year olds) had a wonderful stay. Convenient to airport, less than a mile to El Centro attractions. Even the library, 3 blocks away, is worth a visit! There's plenty to do and plenty to eat. There are a wealth of food stands and a fantastic bakery on the street near the Balderas subway. Also two cafes across the street and an OXXO (convenience store) within a block. Hotel San Diego, across the street, can be a pick-up spot if you book any tour services online.
The apartment (up 3 flights of stairs) has a convenient kitchen, room to relax, and two nice bedrooms right off the living area. We liked the narrow balcony and air flow, but there's plenty of street noise - including the vendor selling Tamales until midnight!
Check-in was easy, and the host (Diego) responded within a couple hours to any texts. It would have been helpful to have a short list of basic instructions at check-in. Otherwise, thank you for a delightful first visit to Mexico City!
