Worked remotely here for 2 weeks. Internet is fast and reliable. My wife and I were on video call the whole time and never once had an issue. The internet was faster than my home in Seattle.
Location, Location, Location. Very safe neighborhood and the building has security on site 24/7-- most of the time multiple at entrances and throughout the building. They are all friendly and really made us feel extra safe. It's right next to a university. Within a 10 minute walk is some of the best food CDMX has to offer. Tons of street food, restaurants and places to get a drink. Right next door is a speak-easy cocktail bar called Ololo, super cool.
The beds are most definitely a bit smaller than the listing says, so if you're traveling with a family and expect the kids to sleep in the same bed it might be tight.
Other than that, incredible spot and if I return to CDMX I'd def. stay here again.
