Here is my honest review. This Airbnb ruined my time in Santiago, unfortunately. The place was not clean and a lot older than the photos. The noise from outside comes in as there is no insulation in the windows. The towels smelled as well as the beddings. The shower water pressure was really low, and the kitchenware was really dirty.
The biggest deal breaker was the extremely loud air conditioner. And, I mean really loud that you cannot work remotely nor sleep with the air conditioner on. It is 33C and is impossible to stay comfortable without the air conditioner.
I ended up staying for only one night and contacted the Airbnb support to move to another Airbnb. As a nomad, I've stayed at many Airbnb (over 35) up to now, and this place was the worst.
