Great authentic introduction to my first time in Mexico City. Location is great. Located in the Historic Center. 2 min walk away from a great rooftop restaurant called, El Mayor. Our apartment was located on the 3rd floor out of 4, with a rooftop. Rooftop includes a small gym, bathroom, outdoor/indoor seating, grill, and great views. The building feels safe, as there is a front desk attendant at all times.
As for the apartment, it is a good size for a couple. Mostly equipped kitchen, I cooked everyday, no dishwasher, but it does have an all-in-one washer/dryer. It also have an oven and a nice Nescafe Dolce Gusto coffee maker. The apartment is not equipped with A/C for the night sweaters like me, but there is a small fan provided and plenty of windows you can open. If you enjoy hot showers like me, rejoice, the water stays hot for a while. During the day, it can get a bit noisy outside, but it didn't bother me while working.
Easy to hail a taxi, Uber, or a new app called Beat, they have a fleet of Tesla Model 3s (electric cars) they will pick you up in, and it's generally cheaper than Uber.
Most importantly, Wi-Fi speeds were phenomenal (80+mbps) and stable.
