Jack and Alice's place is a wonderful, spotless, safe, family-friendly, and relaxing apartment to stay at. My family and I truly enjoyed eating dinner on the terrace. We did not experience any issues with the apartment itself and would definitely stay there again. Alice was always very attentive and thoughtful and always responded to our questions promptly. The location is perfect the Zocalo is literally two blocks away. At the Zocalo is the Metro stop that can take you all over the city, there is also a Metro Bus stop a couple of blocks away that can connect you to adjacent Metro Bus lines. (You need a rechargeable card for the Metro Bus.)
This was a family trip and honestly, we did not find a need to use any transportation within the area. The Centro Historico has plenty to see and do. However, if you enjoy walking La Ciudadela is a 30-minute walk, Palacio de Bellas Arte is a 20-minute walk as is the Barrio Chino. I highly recommend walking down 16 de Septiembre when you are done with the Barrio Chino as you get closer to the Zocalo you will encounter a lot of street performers that make you stop and just enjoy the music. The area where the apartment is located is super safe. The restaurant Elkar is open relatively late and its roasted chicken dinner is a great value. The bakery Madrid down the block opens early and offers great breakfast, lunch and dinner items. During our stay, we saw a fruit truck arrive in front of the bakery and we were able to purchase fresh fruit for our stay. Jack and Alice's place is a great place to stay if you want to truly enjoy the Centro Historico.
