We had a great week in Mexico City! We did not meet Francisco but his friend Guillermo met us promptly and let us in the apartment. There is a double lock to enter the complex so we felt very secure. The home was very comfortable and met all our expectations. The neighborhood is quiet. There is a little shop for basic needs right around the corner and a large grocery store that includes clothing and household items within a 10 to 15 min walk. We only used the subway once but line 1 is very close by. We used Uber for almost all our transportation. It was about 80 pesos to get down to the central district ($4 US) so for four of us that was a bargain. Uber drivers were all very friendly. We even took an Uber to Teotihuacan for about 500 pesos for 4 of us (1 hour drive) which was about the same as bus fare. To come back we used Uber as well (had to wait about 10 minutes for pickup...much better than waiting for the bus). On Sundays they close down the Peseo de la Reforma to traffic so that is a great day to take a walk down that wide boulevard. You can walk from Chulpultepec Castle all the way to the National Palace which would take about an hour. Monday is a good day to go to Teotihuacon since on that day some things are close (Palace Mayor). Highly recommend going into the Gran Hotel (just off the main square and going up to the 4th floor and eating at their terrance restaurant about 5 pm. From there you can watch them take down the flag and enjoy a great view of the square. The food and service were also very good. Everywhere we ate we always had too much food. Also the Tiffany ceiling in the hotel's main lobby is beautiful. If you want the full local experience check out Lucha Libre (wrestling) at the Arena Mexico on Friday nights. We bought our tickets online via Ticketmaster (good seats for 240 pesos per person...$12 US) two days before and picked them up at will call without any problems (showed purchasing credit card, drivers license and signed a couple forms).
