My boyfriend and I stayed here for a week and couldn't have asked for a better stay! The check-in process was a breeze, the building was very secure, the apartment was so roomy and had several french doors we left open nearly the entire time. The location was perfect -- we were no more than a 15 minute walk to every restaurant we wanted to go to, but most were less than 10 minutes away. The Local Way was extremely communicative -- I don't think we waited more than 15 minutes for a response from them throughout the trip. One thing they didn't mention until arrival, which was a huge perk, is that there's free cleaning service included every other day. We didn't end up using it because it was just us, but it was a pleasant surprise nonetheless.
The only two things I'd say is to be prepared that CDMX is noisy, even on quiet streets like ours. We slept with the doors open most nights and were fine, but if you're not used to city noise (we're from NYC) then it may be tough. The second thing is that the shower is very small and may be difficult for someone on the taller side.
Overall, we would totally stay here again!
