The apartment is just as described, clean, new and stylish.
There's a nice collection of Mexican books which made part of my bedtime read. but if you prefer to chill out with a film, they also have Netflix. I loved that you don't need a key to get in as there is a security guy at the entrance that opens the front door for you and welcomes you with a smile. After, the door to the flat is with a security code.
The location is great! I even walked to the city center on my first day. There are restaurants and convenience shops nearby. There is a lovely breakfast place recommended by the hosts at a short walk away.. Metro is less than 10' walk.
The street vendors do cry out loud in the morning, but I didn't mind as it's part of the day to day city life...
What I missed was having a mirror in the bedroom to do my makeup. There is a mirror in the bathroom but as we were 3 people we had to take turns to use it, which took longer in the morning to get ready.
The hosts are very helpful and wrote to me regularly to check I was OK which was nice.
Overall I must say I loved CDMX and I would definitely stay here again!
