Our first trip to Mexico City and we love it in no small part because of Luci's home and the neighborhood in which it is located. We loved Coyoacan because it is an upscale neighborhood with cobbled streets and a vibrant center, but not pretentious. Just regular folk in a beautiful neighborhood. Uber to the center of Mexico city is about a half hour, and we found this the perfect place to come home and unwind.
The apartment itself is full of natural light from skylights, windows, and french doors opening onto a lovely patio. Both bathrooms are very nicely remodeled, clean and bright. There is a bit of street noise, but I am not sure how you could avoid that in a big city. There is a delightful park just across the street, and the town square is a pleasant 10-15 minute walk. From there, you can explore in several different directions and find hidden gems as you go along.
Luci has created a short but outstanding guide to the city center as well as the local environs. We basically used it as our guide the whole time we were there and we were not disappointed.
The coffee shop she (correctly) specifies in her guide as the best in town is staffed by friendly, attentive and knowledgeable baristas.
Note that there is a flight of stairs to get to the apartment. Not a big deal for us, but may not be for everyone.
