Stayed for a month as a remote worker. Wifi speed: 30 Mbps down, 12 Mbps up
Check-in was easy since there are lockboxes. Be aware there's one flight of stairs and not handicap accessible. The apartment is a good size with a nice desk for working. The bathroom includes a hot tub but space is a bit tight if more than 1 person is in it at a time. Kitchen includes a small refrigerator with a very small freezer section only big enough for ice tray so don't plan on buying many frozen foods. The bed is pretty firm and took me a while to get used to sleeping on. If you require a soft bed, this might not be the place for you. Oven, stove and tv all functioned great.
Israel is a very accommodating host. We had some wifi issues but Israel actually brought us another network router to get a stronger signal to use the wifi in the building. The location is in a local neighborhood but Aragon metro station is a 2 block walk and if you are looking for a place to stay near the airport and away from centro then this is a great location.
I would recommend staying here if you aren't looking to spend a lot of time in the tourist areas of Mexico City. We were glad to be able to enjoy some of the local vendors and food is really cheap in this area.
