The hotel is under construction, but not regular construction, to the level on which we went to our room at 2:00PM on our second day, trying to rest of a long walk on the city, to found a cloud of drywall dust on the entire room.
We had problems beathing, so we couldn't rest and had to go out.
During the night the dust was not that visible, but you could smell it and see it over every single piece of furniture.
On top of that, they had no A/C, so you have to sleep with the window open on a room facing a busy avenue of Mexico City.
They most likely don't even pas a regular inspection, the Smoke detectors were cover, I guess to prevent accidental triggering due to the dust.
It was by far the worst hotel I been on my life. We didn't want to ruin our 3 days on the city having to look for another hotel on a busy weekend (OASIS was playing that Saturday), but they should close that hotel until construction is fully finish and should refund our money.
