Couple things that should be noted.
1) The apartment unit listed under location details after booking was not the one I was assigned. Looked the same, but it's a different apartment.
2) Bathroom shower does not drain properly, so water stagnates after showers.
3) The host is not responsive. I noted several issues as soon as I arrived to the host via the airbnb app, but did not receive a response for 8-9 hours. By that point, it was the end of the day and the situation could not be addressed until the next day.
4) The AC did not work. This was one of the issues I flagged to the host, and she sent someone to repair it the next morning. They came and did something, so the AC at least turned on but even then was only set to a "fan" mode so there still was no cold air coming out - just extremely light room temperature air.
5) Fridge didn't work either, both when I checked in and after the mechanic "fixed" it.
Location is convenient enough, since you're close to roma norte and can walk to condesa. Should flag however that this is a 3rd floor walkup. The guard also does not speak english and has no way to contact the host in case of any issues. Other than the issues pointed out above, room itself is just fine - neat enough for a quick stay.
Overall, stay was fine. You're probably better off staying elsewhere, as there are plenty of alternatives, unless you manage to get this listing for a discount and are not looking for accommodations that have better service.
