Alec's apartment was clean and safe, as shown in pictures. Check-in was fast and easy.
We found it was perfect for two couples, especially because it has two full bathrooms. There is also a futon, but I would not recommend having more than four people stay here. It is comfortable but not spacious. We were traveling and spent most of our time out and about exploring the city, so the apartment suited our needs perfectly.
Alec left two large jugs of purified water for us to drink while there. This is a must if you are visiting from another country, and it was nice to not have to worry about it.
The apartment is located in a walkable area -- we loved the neighborhood and enjoyed exploring on foot and walking to coffee, dinner, etc. However, it is not super close to Mexico City's most popular attractions, so you will need to plan for Ubers (inexpensive) or schedule plenty of time for long walks (although long-distance walking can be challenging at altitude if you are not used to it).
Just a heads up that the apartment is close to a main street with traffic 24 hours/day, so it can be a bit noisy at night. Alec very thoughtfully provided earplugs and a white noise machine. Our baby slept just fine, but she is used to a white noise machine at home too. If you are a very light sleeper, this location might not work for you.
